limit: The empirical stick profile converges to a weak
solution of the inviscid Burgers equation under a
scaling of lattice space and time. The stick process is
also an alternative view of Hammersley's particle
system that Aldous and Diaconis used to give a new
solution to Ulam's problem. Along the way to the
scaling limit we produce another independent solution
to this question. The heart of the proof is that
individual paths of the stochastic process evolve under
a semigroup action which under the scaling turns into
the corresponding action for the Burgers equation,
known as the Lax formula. In a separate appendix we use
the Lax formula to give an existence and uniqueness

interactions guarantees that we are in the diffusive
clustering regime, that is spatial clusters of
components with values all close to 0 or all close to 1
grow in various different scales. We studied this
phenomenon in [FG94]. In the present paper we analyze
the evolution of single components and of clusters over
time. First we focus on the time picture of a single
component and find that components close to 0 or close
to 1 at a late time have had this property for a large
time of random order of magnitude, which nevertheless
is small compared with the age of the system. The
asymptotic distribution of the suitably scaled duration
a component was close to a boundary point is
calculated. Second we study the history of spatial 0-
or 1-clusters by means of time scaled block averages
and time-space-thinning procedures. The scaled age of a
cluster is again of a random order of magnitude. Third,
we construct a transformed Fisher--Wright tree, which
(in the long-time limit) describes the structure of the
space-time process associated with our system. All
described phenomena are independent of the diffusion
coefficient and occur for a large class of initial
configurations (universality).",

Roughly, an extreme version is specified by translation

relative sizes of large clusters at time $ - \infty $.
Such a version may be characterized in three ways: via
its $ t \to - \infty $ behavior, via a representation
of the marginal distribution $ X(t)$ in terms of
excursion-lengths of a L{\'e}vy-type process, or via a
weak limit of processes derived from the standard

\lambda_2 (t))$, is a recurrent diffusion. Neither
curvature by itself is a diffusion. In a separate

codimension one submanifold of $ R^n$. In this case,
there are $ n - 1$ principal curvatures $ \lambda_1

in a $ d + 1$ dimensional space. For each $ x \in Z^d$,
let $ \eta_t(x) \in R$ be the height of the surface at
site $x$ at time $t$. At rate $1$ the $x$-th height is
updated to a random convex combination of the heights
of the `neighbors' of $x$. The distribution of the
convex combination is translation invariant and does
not depend on the heights. This motion, named the
random average process (RAP), is one of the linear
processes introduced by Liggett (1985). Special cases
of RAP are a type of smoothing process (when the convex
combination is deterministic) and the voter model (when
the convex combination concentrates on one site chosen
at random). We start the heights located on a
hyperplane passing through the origin but different
from the trivial one $ \eta (x) \equiv 0$. We show
that, when the convex combination is neither
deterministic nor concentrating on one site, the
variance of the height at the origin at time $t$ is
proportional to the number of returns to the origin of
a symmetric random walk of dimension $d$. Under mild
conditions on the distribution of the random convex
combination, this gives variance of the order of $ t^{1
/ 2}$ in dimension $ d = 1$, $ \log t$ in dimension $ d
= 2$ and bounded in $t$ in dimensions $ d \ge 3$. We
also show that for each initial hyperplane the process
as seen from the height at the origin converges to an
invariant measure on the hyper surfaces conserving the
initial asymptotic slope. The height at the origin
satisfies a central limit theorem. To obtain the
results we use a corresponding probabilistic cellular
automaton for which similar results are derived. This
automaton corresponds to the product of (infinitely

almost sure limit theorems motivated by the notion of
average densities introduced by Bedford and Fisher. We
show that in 3-space the intersection local time
measure of two paths has an average density of order
two with respect to the gauge function $ \varphi (r) =
r $, but in the plane, for the intersection local time
measure of p Brownian paths, the average density of
order two fails to converge. The average density of
order three, however, exists for the gauge function $
\varphi_p(r) = r^2 [\log (1 / r)]^p $. We also prove
refined versions of the above results, which describe
more precisely the fluctuations of the volume of small

where $ \text {dim}_p E$ is the {\em packing dimension}
of $E$. We derive this from a general result that
applies to many other random fractals defined by limsup
operations. This result also yields extensions of
certain ``fractal functional limit laws'' due to
Deheuvels and Mason (1994). In particular, we prove
that for any absolutely continuous function $f$ such
that $ f(0) = 0$ and the energy $ \int_0^1 |f'|^2 \, d

a.s. exists some $ t \in E$ so that $f$ can be
uniformly approximated in $ [0, 1]$ by normalized
Brownian increments $ s \mapsto [X(t + s h) - X(t)] /

a.s. impossible if the energy of $f$ is higher than the

coupled PDE system. It provides both a detailed
treatment of the {\em existence\/} and {\em
uniqueness\/} of monotone travelling waves to various
equilibria, by differential-equation theory and by
probability theory and a treatment of the corresponding
hyperbolic initial-value problem, by analytic methods.
The initial-value problem is studied using
characteristics to show existence and uniqueness of a
bounded solution for bounded initial data (subject to
certain smoothness conditions). The concept of {\em
weak\/} solutions to partial differential equations is
used to rigorously examine bounded initial data with
jump discontinuities. For the travelling wave problem
the differential-equation treatment makes use of a
shooting argument and explicit calculations of the
eigenvectors of stability matrices. The probabilistic
treatment is careful in its proofs of {\em
martingale\/} (as opposed to merely local-martingale)
properties. A modern {\em change-of-measure
technique\/} is used to obtain the best lower bound on
the speed of the monotone travelling wave --- with
Heaviside initial conditions the solution converges to
an approximate travelling wave of that speed (the
solution tends to one ahead of the wave-front and to
zero behind it). Waves to different equilibria are
shown to be related by Doob $h$-transforms. {\em
Large-deviation theory\/} provides heuristic links
between alternative descriptions of minimum wave
speeds, rigorous algebraic proofs of which are

biregular planar graphs then these two problems can be
treated in a similar way and all the above questions
are positively answered. We also give examples to show
that if one drops the assumption of transitivity, then
the answer to the above two questions is no.
Furthermore it is shown that for any bounded-degree
bipartite graph $G$ with $ p_c(G) < 1$ one has $ p_c(G)
< p_d(G)$. Problem (2) arises naturally from [6] where
an example is given of a coupling of the distinct plus-

most interested have discontinuities which persist for
all time, and therefore need to be interpreted as {\em

uniqueness for such weak solutions, identifying a
canonical `{\em exact\/}' solution which is {\em

by the theory of measure-valued diffusions. The method
is more effective than the method of characteristics,
and has the advantage that it leads immediately to the
McKean representation without recourse to It{\^o}'s
formula. We then conduct computer studies of our model,
both by integration schemes (which {\em do\/} use
characteristics) and by `random simulation'.",

This article is about a fundamental and hitherto
neglected property of random vectors of the form $ Y =
f(X(t))$, where $ X(t)$ is the value at time $t$ of a
diffusion process $X$: namely that there exists a
measure of location, called the ``intrinsic location
parameter'' (ILP), which coincides with mathematical
expectation only in special cases, and which is
invariant under change of coordinate systems. The
construction uses martingales with respect to the
intrinsic geometry of diffusion processes, and the heat
flow of harmonic mappings. We compute formulas which
could be useful to statisticians, engineers, and others
who use diffusion process models; these have immediate
application, discussed in a separate article, to the
construction of an intrinsic nonlinear analog to the
Kalman Filter. We present here a numerical simulation
of a nonlinear SDE, showing how well the ILP formula
tracks the mean of the SDE for a Euclidean geometry.",

processes on the lattice $ Z^d $. These are on the one
hand side a particle system, called branching random
walk, and on the other hand its continuous mass
analogue, a system of interacting diffusions also
called super random walk. It is known that the
long-term behavior differs sharply in low and high
dimensions: if $ d \leq 2 $ one gets local extinction,
while, for $ d \geq 3 $, the systems tend to a
non-trivial equilibrium. Due to Kallenberg's criterion,
local extinction goes along with clumping around a
'typical surviving particle.' This phenomenon is called
clustering. A detailed description of the clusters has
been given for the corresponding processes on $ R^2 $
in Klenke (1997). Klenke proved that with the right
scaling the mean number of particles over certain
blocks are asymptotically jointly distributed like
marginals of a system of coupled Feller diffusions,
called system of tree indexed Feller diffusions,
provided that the initial intensity is appropriately
increased to counteract the local extinction. The
present paper takes different remedy against the local
extinction allowing also for state-dependent branching
mechanisms. Instead of increasing the initial
intensity, the systems are described under the Palm
distribution. It will turn out together with the
results in Klenke (1997) that the change to the Palm
measure and the multiple scale analysis commute, as $ t
\to \infty $. The method of proof is based on the fact
that the tree indexed systems of the branching
processes and of the diffusions in the limit are
completely characterized by all their moments. We
develop a machinery to describe the space-time moments
of the superprocess effectively and explicitly.",

systems with spatial components (colonies) indexed by a
countable group, for example $ Z^d $ or the
hierarchical group. As type space we allow continua and
describe populations in one colony as measures on the
type space. The spatial components of the system
interact via migration. Instead of the classical
independence assumption on the evolution of different
families of the branching population, we introduce
interaction between the families through a state
dependent branching rate of individuals and in addition
state dependent mean offspring of individuals. However
for most results we consider the critical case in this
work. The systems considered arise as diffusion limits
of critical multiple type branching random walks on a
countable group with interaction between individual
families induced by a branching rate and offspring mean
for a single particle, which depends on the total
population at the site at which the particle in
question is located.\par
The main purpose of this paper is to construct the
measure valued diffusions in question, characterize
them via well-posed martingale problems and finally
determine their longtime behavior, which includes some
new features. Furthermore we determine the dynamics of
two functionals of the system, namely the process of
total masses at the sites and the relative weights of
the different types in the colonies as system of
interacting diffusions respectively time-inhomogeneous
Fleming--Viot processes. This requires a detailed
analysis of path properties of the total mass
processes.\par
In addition to the above mentioned systems of
interacting measure valued processes we construct the
corresponding historical processes via well-posed
martingale problems. Historical processes include
information on the family structure, that is, the
varying degrees of relationship between
individuals.\par
Ergodic theorems are proved in the critical case for
both the process and the historical process as well as
the corresponding total mass and relative weights
functionals. The longtime behavior differs
qualitatively in the cases in which the symmetrized
motion is recurrent respectively transient. We see
local extinction in one case and honest equilibria in
the other.\par
This whole program requires the development of some new
techniques, which should be of interest in a wider
context. Such tools are dual processes in randomly
fluctuating medium with singularities and coupling for
systems with multi-dimensional components.\par
The results above are the basis for the analysis of the
large space-time scale behavior of such branching
systems with interaction carried out in a forthcoming
paper. In particular we study there the universality
properties of the longtime behavior and of the family
(or genealogical) structure, when viewed on large space
and time scales.",

abstract = "Shnerb et al. (2000), (2001) studied the following
system of interacting particles on $ \mathbb {Z}^d $:
There are two kinds of particles, called $A$-particles
and $B$-particles. The $A$-particles perform continuous
time simple random walks, independently of each other.
The jump rate of each $A$-particle is $ D_A$. The
$B$-particles perform continuous time simple random
walks with jump rate $ D_B$, but in addition they die
at rate $ \delta $ and a $B$-particle at $x$ at time
$s$ splits into two particles at $x$ during the next $
d s$ time units with a probability $ \beta N_A(x, s)d s
+ o(d s)$, where $ N_A(x, s) \; (N_B(x, s))$ denotes
the number of $A$-particles (respectively
$B$-particles) at $x$ at time $s$. Conditionally on the
$A$-system, the jumps, deaths and splittings of
different $B$-particles are independent. Thus the
$B$-particles perform a branching random walk, but with
a birth rate of new particles which is proportional to
the number of $A$-particles which coincide with the
appropriate $B$-particles. One starts the process with
all the $ N_A(x, 0), \, x \in \mathbb {Z}^d$, as
independent Poisson variables with mean $ \mu_A$, and
the $ N_B(x, 0), \, x \in \mathbb {Z}^d$, independent
of the $A$-system, translation invariant and with mean
$ \mu_B$.\par
Shnerb et al. (2000) made the interesting discovery
that in dimension 1 and 2 the expectation $ \mathbb {E}
\{ N_B(x, t) \} $ tends to infinity, {\em no matter
what the values of } $ \delta, \beta, D_A$, $ D_B,
\mu_A, \mu_B \in (0, \infty)$ {\em are}. We shall show
here that nevertheless {\em there is a phase transition
in all dimensions}, that is, the system becomes
(locally) extinct for large $ \delta $ but it survives
for $ \beta $ large and $ \delta $ small.",

dimension restriction. The competing species model
describes the evolution of two populations where
individuals of different types may kill each other if
they collide. In the case of Brownian migration and
finite variance branching, the model was introduced by
Evans and Perkins (1994). The fact that now the
branching mechanism does not have finite variance

the collision local time which we believe are of some

\partial t = \pm \partial^n u / \partial x^n $ has been
investigated by many authors. With this equation is
associated a pseudo-process $ (X_t)_{t \ge 0} $ which
is governed by a signed measure. In the even-order
case, Krylov (1960) proved that the classical arc-sine
law of Paul Levy for standard Brownian motion holds for
the pseudo-process $ (X_t)_{t \ge 0} $, that is, if $
T_t $ is the sojourn time of $ (X_t)_{t \ge 0} $ in the
half line $ (0, + \infty) $ up to time $t$, then $
P(T_t \in d s) = \frac {ds}{\pi \sqrt {s(t - s)}}$, $ 0
< s < t$. Orsingher (1991) and next Hochberg and
Orsingher (1994) obtained a counterpart to that law in
the odd cases $ n = 3, 5, 7.$ Actually Hochberg and
Orsingher (1994) proposed a more or less explicit
expression for that new law in the odd-order general
case and conjectured a quite simple formula for it. The
distribution of $ T_t$ subject to some conditioning has
also been studied by Nikitin \& Orsingher (2000) in the
cases $ n = 3, 4.$ In this paper, we prove that the
conjecture of Hochberg and Orsingher (1994) is true and
we extend the results of Nikitin \& Orsingher for any
integer $n$. We also investigate the distributions of
maximal and minimal functionals of $ (X_t)_{t \ge 0}$,
as well as the distribution of the last time before
becoming definitively negative up to time $t$.",

deviation principle for solutions of stochastic
equations with possibly degenerate coefficients.
Specifically, we explore the potential of the
methodology that consists in establishing exponential
tightness and identifying the action functional via a
maxingale problem. In the author's earlier work it has
been demonstrated that certain convergence properties
of the predictable characteristics of semimartingales
ensure both that exponential tightness holds and that
every large deviation accumulation point is a solution
to a maxingale problem. The focus here is on the
uniqueness for the maxingale problem. It is first shown
that under certain continuity hypotheses existence and
uniqueness of a solution to a maxingale problem of
diffusion type are equivalent to Luzin weak existence
and uniqueness, respectively, for the associated
idempotent It{\^o} equation. Consequently, if the
idempotent equation has a unique Luzin weak solution,
then the action functional is specified uniquely, so
the large deviation principle follows. Two kinds of
application are considered. Firstly, we obtain results
on the logarithmic asymptotics of moderate deviations
for stochastic equations with possibly degenerate
diffusion coefficients which, as compared with earlier
results, relax the growth conditions on the
coefficients, permit certain non-Lipshitz-continuous
coefficients, and allow the coefficients to depend on
the entire past of the process and to be discontinuous
functions of time. The other application concerns
multiple-server queues with impatient customers.",

Brownian motions starting from every point in space and
time $ R \times R $. It was first introduced by
Arratia, and later analyzed in detail by Toth and
Werner. More recently, Fontes, Isopi, Newman and
Ravishankar (FINR) gave a characterization of the BW,
and general convergence criteria allowing in principle
either crossing or noncrossing paths, which they
verified for coalescing simple random walks. Later
Ferrari, Fontes, and Wu verified these criteria for a
two dimensional Poisson Tree. In both cases, the paths
are noncrossing. To date, the general convergence
criteria of FINR have not been verified for any case
with crossing paths, which appears to be significantly
more difficult than the noncrossing paths case.
Accordingly, in this paper, we formulate new
convergence criteria for the crossing paths case, and
verify them for non-simple coalescing random walks
satisfying a finite fifth moment condition. This is the
first time that convergence to the BW has been proved
for models with crossing paths. Several corollaries are
presented, including an analysis of the scaling limit
of voter model interfaces that extends a result of Cox
and Durrett.",

abstract = "In this paper we continue the investigation of the
spectral theory and exponential asymptotics of
primarily discrete-time Markov processes, following
Kontoyiannis and Meyn (2003). We introduce a new family
of nonlinear Lyapunov drift criteria, which
characterize distinct subclasses of geometrically
ergodic Markov processes in terms of simple
inequalities for the nonlinear generator. We
concentrate primarily on the class of multiplicatively
regular Markov processes, which are characterized via
simple conditions similar to (but weaker than) those of
Donsker--Varadhan. For any such process $ \{ \Phi (t)
\} $ with transition kernel $P$ on a general state
space $X$, the following are obtained. Spectral Theory:
For a large class of (possibly unbounded) functionals
$F$ on $X$, the kernel $ \hat P(x, d y) = e^{F(x)} P(x,
d y)$ has a discrete spectrum in an appropriately
defined Banach space. It follows that there exists a
``maximal, '' well-behaved solution to the
``multiplicative Poisson equation, '' defined as an
eigenvalue problem for $ \hat P$. Multiplicative Mean
Ergodic Theorem: Consider the partial sums of this
process with respect to any one of the functionals $F$
considered above. The normalized mean of their moment
generating function (and not the logarithm of the mean)
converges to the above maximal eigenfunction
exponentially fast. Multiplicative regularity: The
Lyapunov drift criterion under which our results are
derived is equivalent to the existence of regeneration
times with finite exponential moments for the above
partial sums. Large Deviations: The sequence of
empirical measures of the process satisfies a large
deviations principle in a topology finer that the usual
tau-topology, generated by the above class of
functionals. The rate function of this LDP is the
convex dual of logarithm of the above maximal
eigenvalue, and it is shown to coincide with the
Donsker--Varadhan rate function in terms of relative
entropy. Exact Large Deviations Asymptotics: The above
partial sums are shown to satisfy an exact large
deviations expansion, analogous to that obtained by
Bahadur and Ranga Rao for independent random
variables.",

two, somewhat different, thinning models. The main

use an alternative thinning model, which can be more

Borel measurable function. We are interested in finding
conditions on $X$ and $f$ which imply that the
perpetual integral functional\par
$$ I^X_\infty (f) := \int_0^\infty f(X_t) d t $$
is identical in law with the first hitting time of a
point for some other diffusion. This phenomenon may
often be explained using random time change. Because of
some potential applications in mathematical finance, we
are considering mainly the case when $X$ is a Brownian
motion with drift $ \mu > 0, $ denoted $ {B^{(\mu)}_t
\colon t \geq 0}, $ but it is obvious that the method
presented is more general. We also review the known
examples and give new ones. In particular, results
concerning one-sided functionals\par
$$ \int_0^\infty f(B^{(\mu)}_t){\bf 1}_{{B^{(\mu)}_t <
0}} d t \quad {\rm and} \quad \int_0^\infty
f(B^{(\mu)}_t){\bf 1}_{{B^{(\mu)}_t > 0}} d t $$
are presented. This approach generalizes the proof,
based on the random time change techniques, of the fact
that the Dufresne functional (this corresponds to $
f(x) = \exp ( - 2 x)), $ playing quite an important
role in the study of geometric Brownian motion, is
identical in law with the first hitting time for a
Bessel process. Another functional arising naturally in
this context is\par
$$ \int_0^\infty \big (a + \exp (B^{(\mu)}_t)
\big)^{-2} d t, $$
which is seen, in the case $ \mu = 1 / 2, $ to be
identical in law with the first hitting time for a
Brownian motion with drift $ \mu = a / 2.$ The paper is
concluded by discussing how the Feynman--Kac formula
can be used to find the distribution of a perpetual

consisting of a bank of buffers for holding incoming

several different classes (or buffers). Jobs within a
class are processed on a first-in-first-out basis,
where the processing of a given job may be performed by
any server from a given (class-dependent) subset of the
bank of servers. The random service time of a job may
depend on both its class and the server providing the
service. Each job departs the system after receiving
service from one server. The system manager seeks to
minimize holding costs by dynamically scheduling
waiting jobs to available servers. We consider a
parameter regime in which the system satisfies both a
heavy traffic and a complete resource pooling
condition. Our cost function is an expected cumulative
discounted cost of holding jobs in the system, where
the (undiscounted) cost per unit time is a linear
function of normalized (with heavy traffic scaling)
queue length. In a prior work, the second author
proposed a continuous review threshold control policy
for use in such a parallel server system. This policy
was advanced as an ``interpretation'' of the analytic
solution to an associated Brownian control problem
(formal heavy traffic diffusion approximation). In this
paper we show that the policy proposed previously is
asymptotically optimal in the heavy traffic limit and
that the limiting cost is the same as the optimal cost

abstract = "We consider spatially interacting Moran models and
their diffusion limit which are interacting
Fisher--Wright diffusions. The Moran model is a spatial
population model with individuals of different type
located on sites given by elements of an Abelian group.
The dynamics of the system consists of independent
migration of individuals between the sites and a
resampling mechanism at each site, i.e., pairs of
individuals are replaced by new pairs where each
newcomer takes the type of a randomly chosen individual
from the parent pair. Interacting Fisher--Wright
diffusions collect the relative frequency of a subset
of types evaluated for the separate sites in the limit
of infinitely many individuals per site. One is
interested in the type configuration as well as the
time-space evolution of genealogies, encoded in the
so-called historical process. The first goal of the
paper is the analytical characterization of the
historical processes for both models as solutions of
well-posed martingale problems and the development of a
corresponding duality theory. For that purpose, we link
both the historical Fisher--Wright diffusions and the
historical Moran models by the so-called look-down
process. That is, for any fixed time, a collection of
historical Moran models with increasing particle
intensity and a particle representation for the
limiting historical interacting Fisher--Wright
diffusions are provided on one and the same probability
space. This leads to a strong form of duality between
spatially interacting Moran models, interacting
Fisher--Wright diffusions on the one hand and
coalescing random walks on the other hand, which
extends the classical weak form of moment duality for
interacting Fisher--Wright diffusions. Our second goal
is to show that this representation can be used to
obtain new results on the long-time behavior, in
particular (i) on the structure of the equilibria, and
of the equilibrium historical processes, and (ii) on
the behavior of our models on large but finite site
space in comparison with our models on infinite site
space. Here the so-called finite system scheme is
established for spatially interacting Moran models
which implies via the look-down representation also the
already known results for interacting Fisher--Wright
diffusions. Furthermore suitable versions of the finite
system scheme on the level of historical processes are
newly developed and verified. In the long run the
provided look-down representation is intended to answer
questions about finer path properties of interacting
Fisher--Wright diffusions.",

calculated directly or in two steps backwards in time.
We show that this condition translates into a
decomposition property for the corresponding acceptance
sets, and we demonstrate how time-consistent dynamic
monetary risk measures can be constructed by pasting
together one-period risk measures. For conditional
coherent and convex monetary risk measures, we provide
dual representations of Legendre--Fenchel type based on
linear functionals induced by adapted increasing
processes of integrable variation. Then we give dual
characterizations of time-consistency for dynamic
coherent and convex monetary risk measures. To this
end, we introduce a concatenation operation for adapted
increasing processes of integrable variation, which
generalizes the pasting of probability measures. In the
coherent case, time-consistency corresponds to
stability under concatenation in the dual. For dynamic
convex monetary risk measures, the dual
characterization of time-consistency generalizes to a
condition on the family of convex conjugates of the
conditional risk measures at different times. The
theoretical results are applied by discussing the
time-consistency of various specific examples of

motivated a substantial number of new and sometimes
quite difficult studies of reinforcement models in pure

models related to this has caused the original
unpublished manuscript to be frequently cited, despite
its lack of availability and the presence of errors.

approximates the ground state of a certain dilute large
quantum system; the kinetic energy term of that formula

press], we highlight condition $ (T) $ as a source of
new examples of 'ballistic' diffusions in a random
environment when $ d > 1 $ ('ballistic' means that a
strong law of large numbers with non-vanishing limiting
velocity holds). In particular we are able to treat the
case of non-constant diffusion coefficients, a feature
that causes problems. Further we recover the ballistic
character of two important classes of diffusions in a
random environment by simply checking condition $ (T)
$. This not only points out to the broad range of
examples where condition $ (T) $ can be checked, but
also fortifies our belief that condition $ (T) $ is a
natural contender for the characterisation of ballistic
diffusions in a random environment when $ d > 1 $.",

function with respect to the unique invariant measure
of the diffusion process, as a function of the
attraction point. Such mappings arise in the analysis
of infinite systems of diffusions indexed by the
hierarchical group, with a linear attractive
interaction between the components. In this context,
the mappings are called renormalization
transformations. We consider such maps for catalytic
Wright--Fisher diffusions. These are diffusions on the
unit square where the first component (the catalyst)
performs an autonomous Wright--Fisher diffusion, while
the second component (the reactant) performs a
Wright--Fisher diffusion with a rate depending on the
first component through a catalyzing function. We
determine the limit of rescaled iterates of
renormalization transformations acting on the diffusion
matrices of such catalytic Wright--Fisher diffusions.",

the coagulation kernel grows sufficiently fast so that
the phenomenon of gelation is observed. Weak
accumulation points of an appropriate sequence of

solutions of a nonlinear equation. A natural
description of the behavior of the gel is obtained by
using the one-point compactification of the size space.
Two aspects of the limiting equation are of special
interest. First, for a certain class of coagulation
kernels, this equation differs from a naive extension
of Smoluchowski's coagulation equation. Second, due to
spatial inhomogeneity, an equation for the time
evolution of the gel mass density has to be added. The
jump rates are assumed to vanish with increasing
particle masses so that the gel is immobile. Two
different gel growth mechanisms (active and passive
gel) are found depending on the type of the coagulation

(ESP) and associated extended Skorokhod map (ESM) that
enable a pathwise construction of reflected diffusions
that are not necessarily semimartingales. Roughly
speaking, given the closure $G$ of an open connected
set in $ {\mathbb R}^J$, a non-empty convex cone $ d(x)
\subset {\mathbb R}^J$ specified at each point $x$ on
the boundary $ \partial G$, and a c{\`a}dl{\`a}g
trajectory $ \psi $ taking values in $ {\mathbb R}^J$,
the ESM $ \bar \Gamma $ defines a constrained version $
\phi $ of $ \psi $ that takes values in $G$ and is such
that the increments of $ \phi - \psi $ on any interval
$ [s, t]$ lie in the closed convex hull of the
directions $ d(\phi (u)), u \in (s, t]$. When the graph
of $ d(\cdot)$ is closed, the following three
properties are established: (i) given $ \psi $, if $
(\phi, \eta)$ solve the ESP then $ (\phi, \eta)$ solve
the corresponding Skorokhod problem (SP) if and only if
$ \eta $ is of bounded variation; (ii) given $ \psi $,
any solution $ (\phi, \eta)$ to the ESP is a solution
to the SP on the interval $ [0, \tau_0)$, but not in
general on $ [0, \tau_0]$, where $ \tau_0$ is the first
time that $ \phi $ hits the set $ {\cal V}$ of points $
x \in \partial G$ such that $ d(x)$ contains a line;
(iii) the graph of the ESM $ \bar \Gamma $ is closed on
the space of c{\`a}dl{\`a}g trajectories (with respect
to both the uniform and the $ J_1$-Skorokhod
topologies).\par
The paper then focuses on a class of multi-dimensional
ESPs on polyhedral domains with a non-empty $ {\cal
V}$-set. Uniqueness and existence of solutions for this
class of ESPs is established and existence and pathwise
uniqueness of strong solutions to the associated
stochastic differential equations with reflection is
derived. The associated reflected diffusions are also
shown to satisfy the corresponding submartingale
problem. Lastly, it is proved that these reflected
diffusions are semimartingales on $ [0, \tau_0]$. One
motivation for the study of this class of reflected
diffusions is that they arise as approximations of
queueing networks in heavy traffic that use the
so-called generalised processor sharing discipline.",

close connection between return (resp. waiting) times

entropy rather than entropy. In this paper we elaborate
on this in the case of continuous-time Markov processes
with finite state space. A reference measure of special
interest is the one associated to the time-reversed
process. In that case relative entropy is interpreted
as the entropy production rate. The main results of
this paper are: almost-sure convergence to relative
entropy of the logarithm of waiting-times ratios
suitably normalized, and their fluctuation properties

are located on sites of $ \mathbb {Z} $. A site can be
vacant or be occupied by a tree. Each vacant site
becomes occupied at rate $1$, independently of the
other sites. Each site is hit by lightning with rate $
\lambda $, which burns down the occupied cluster of
that site instantaneously. As $ \lambda \downarrow 0$
this process is believed to display self-organised
critical behaviour.\par
This paper is mainly concerned with the cluster size
distribution in steady-state. Drossel, Clar and Schwabl
(1993) claimed that the cluster size distribution has a
certain power law behaviour which holds for cluster
sizes that are not too large compared to some explicit
cluster size $ s_{max}$. The latter can be written in
terms of $ \lambda $ approximately as $ s_{max} \ln
(s_{max}) = 1 / \lambda $. However, Van den Berg and
Jarai (2005) showed that this claim is not correct for
cluster sizes of order $ s_{max}$, which left the
question for which cluster sizes the power law
behaviour {\em does} hold. Our main result is a
rigorous proof of the power law behaviour up to cluster
sizes of the order $ s_{max}^{1 / 3}$. Further, it
proves the existence of a stationary translation
invariant distribution, which was always assumed but
never shown rigorously in the literature.",

from quite general initial conditions (not in

based on a certain perturbation argument that has been
used in previous works in the same context. In our
asymptotic expansions, however, not only the principal
term but also the second order term are expressed
explicitly in terms of a few basic functions that are
characteristics of the expansion. The second order term
will be important for instance in computation of the
harmonic measures of a half space for certain models.
We introduce a certain aperiodicity condition, named
Condition (AP), that seems a minimal one under which
the Fourier analysis can be applied straightforwardly.
In the case when Condition (AP) is violated the
structure of MA processes will be clarified and it will
be shown that in a simple manner the process, if not
degenerate, are transformed to another one that
satisfies Condition (AP) so that from it we derive
either directly or indirectly (depending on purpose)
the asymptotic expansions for the original process. It
in particular is shown that if the MA processes is
irreducible as a Markov process, then the Green
function is expanded quite similarly to that of a
classical random walk on $ Z^d $.",

abstract = "In this paper, we develop a new ``robust mixing''
framework for reasoning about adversarially modified
Markov Chains (AMMC). Let $ \mathbb {P} $ be the
transition matrix of an irreducible Markov Chain with
stationary distribution $ \pi $. An adversary announces
a sequence of stochastic matrices $ \{ \mathbb {A}_t
\}_{t > 0} $ satisfying $ \pi \mathbb {A}_t = \pi $. An
AMMC process involves an application of $ \mathbb {P} $
followed by $ \mathbb {A}_t $ at time $t$. The robust
mixing time of an ergodic Markov Chain $ \mathbb {P}$
is the supremum over all adversarial strategies of the
mixing time of the corresponding AMMC process.
Applications include estimating the mixing times for
certain non-Markovian processes and for reversible
liftings of Markov Chains.\par
{\bf Non-Markovian card shuffling processes}: The
random-to-cyclic transposition process is a {\em
non-Markovian} card shuffling process, which at time
$t$, exchanges the card at position $ L_t := t {\pmod
n}$ with a random card. Mossel, Peres and Sinclair
(2004) showed a lower bound of $ (0.0345 + o(1))n \log
n$ for the mixing time of the random-to-cyclic
transposition process. They also considered a
generalization of this process where the choice of $
L_t$ is adversarial, and proved an upper bound of $ C n
\log n + O(n)$ (with $ C \approx 4 \times 10^5$) on the
mixing time. We reduce the constant to $1$ by showing
that the random-to-top transposition chain ({\em a
Markov Chain}) has robust mixing time $ \leq n \log n +
O(n)$ when the adversarial strategies are limited to
holomorphic strategies, i.e., those strategies which
preserve the symmetry of the underlying Markov Chain.
We also show a $ O(n \log^2 n)$ bound on the robust
mixing time of the lazy random-to-top transposition
chain when the adversary is not limited to holomorphic
strategies.\par
{\bf Reversible liftings}: Chen, Lovasz and Pak showed
that for a reversible ergodic Markov Chain $ \mathbb
{P}$, any reversible lifting $ \mathbb {Q}$ of $
\mathbb {P}$ must satisfy $ \mathcal {T}(\mathbb {P})
\leq \mathcal {T}(\mathbb {Q}) \log (1 / \pi_*)$ where
$ \pi_*$ is the minimum stationary probability. Looking
at a specific adversarial strategy allows us to show
that $ \mathcal {T}(\mathbb {Q}) \geq r(\mathbb {P})$
where $ r(\mathbb {P})$ is the relaxation time of $
\mathbb {P}$. This gives an alternate proof of the
reversible lifting result and helps identify cases
where reversible liftings cannot improve the mixing
time by more than a constant factor.",

size-biased Yaglom distribution (of the CB-process).
More generally, we prove that for a wide class of

probability 1, the Yaglom distribution is always
stochastically dominated by the stationary probability
of the $Q$-process, assuming that both exist. Finally,

abstract = "We investigate a possible definition of expectation
and conditional expectation for random variables with
values in a local field such as the $p$-adic numbers.
We define the expectation by analogy with the
observation that for real-valued random variables in $
L^2$ the expected value is the orthogonal projection
onto the constants. Previous work has shown that the
local field version of $ L^\infty $ is the appropriate
counterpart of $ L^2$, and so the expected value of a
local field-valued random variable is defined to be its
``projection'' in $ L^\infty $ onto the
constants.\par
Unlike the real case, the resulting projection is not
typically a single constant, but rather a ball in the
metric on the local field. However, many properties of
this expectation operation and the corresponding
conditional expectation mirror those familiar from the
real-valued case; for example, conditional expectation
is, in a suitable sense, a contraction on $ L^\infty $
and the tower property holds. We also define the
corresponding notion of martingale, show that several
standard examples of martingales (for example, sums or
products of suitable independent random variables or
``harmonic'' functions composed with Markov chains)
have local field analogues, and obtain versions of the
optional sampling and martingale convergence
theorems.",

exponents are trivial when the random walk is
recurrent, but display an interesting dependence on the
diffusion constant when the random walk is transient,
with qualitatively different behavior in different
dimensions. Special attention is given to the
asymptotics of the exponents when the diffusion
constant tends to infinity, which is controlled by
moderate deviations of the random field requiring a
delicate expansion argument.\par

are influenced by mutation, selection and genetic
drift. Provided that the branches of the tree
correspond to lineages belonging to genetically
isolated populations (e.g., multi-species phylogenies),
the interplay between these three processes can be
described by analyzing the process of substitutions to
the common ancestor of each population. We characterize
this process for a class of diffusion models from
population genetics theory using the structured
coalescent process introduced by Kaplan et al. (1988)
and formalized in Barton et al. (2004). For two-allele
models, this approach allows both the stationary
distribution of the type of the common ancestor and the
generator of the common ancestor process to be
determined by solving a one-dimensional boundary value
problem. In the case of a Wright--Fisher diffusion with
genic selection, this solution can be found in closed
form, and we show that our results complement those
obtained by Fearnhead (2002) using the ancestral
selection graph. We also observe that approximations
which neglect recurrent mutation can significantly
underestimate the exact substitution rates when
selection is strong. Furthermore, although we are
unable to find closed-form expressions for models with
frequency-dependent selection, we can still solve the
corresponding boundary value problem numerically and
then use this solution to calculate the substitution
rates to the common ancestor. We illustrate this
approach by studying the effect of dominance on the
common ancestor process in a diploid population.
Finally, we show that the theory can be formally
extended to diffusion models with more than two genetic
backgrounds, but that it leads to systems of singular
partial differential equations which we have been
unable to solve.",

Using a bijection due to Bouttier, Di Francesco and
Guitter between rooted bipartite planar maps and
certain two-type trees with positive labels, we derive
our results from a conditional limit theorem for
two-type spatial trees. Finally we apply our estimates
to separating vertices of bipartite planar maps: with
probability close to one when n tends to infinity, a
random $ 2 k$-angulation with n faces has a separating
vertex whose removal disconnects the map into two
components each with size greater that $ n^{1 / 2 -

the vertex set of one graph to the vertex set of the
other graph, that maps edges to edges. In this note we
study the range of a uniformly chosen homomorphism from
a graph $G$ to the infinite line $Z$. It is shown that
if the maximal degree of $G$ is `sub-logarithmic', then
the range of such a homomorphism is
super-constant.\par
Furthermore, some examples are provided, suggesting
that perhaps for graphs with super-logarithmic degree,
the range of a typical homomorphism is bounded. In
particular, a sharp transition is shown for a specific
family of graphs $ C_{n, k}$ (which is the tensor
product of the $n$-cycle and a complete graph, with
self-loops, of size $k$). That is, given any function $
\psi (n)$ tending to infinity, the range of a typical
homomorphism of $ C_{n, k}$ is super-constant for $ k =
2 \log (n) - \psi (n)$, and is $3$ for $ k = 2 \log (n)

is a mapping $ \varphi $ such that if $ \varphi^k(x) =

Equivalently, $ \varphi^\ell = \varphi^{\ell + 1} =
\ldots $ for $ \ell $ sufficiently large. We
investigate the behavior as $ n \rightarrow \infty $ of
a sequence of a Markov chain on the collection of such
mappings. At each step of the chain, a point in the $n$
element set is chosen uniformly at random and the
current mapping is modified by replacing the current
image of that point by a new one chosen independently
and uniformly at random, conditional on the resulting
mapping being again acyclic. We can represent an
acyclic mapping as a directed graph (such a graph will
be a collection of rooted trees) and think of these
directed graphs as metric spaces with some extra
structure. Informal calculations indicate that the
metric space valued process associated with the Markov
chain should, after an appropriate time and ``space''
rescaling, converge as $ n \rightarrow \infty $ to a
real tree ($R$-tree) valued Markov process that is
reversible with respect to a measure induced naturally
by the standard reflected Brownian bridge. Although we
don't prove such a limit theorem, we use Dirichlet form
methods to construct a Markov process that is Hunt with
respect to a suitable Gromov--Hausdorff-like metric and
evolves according to the dynamics suggested by the
heuristic arguments. This process is similar to one
that appears in earlier work by Evans and Winter as a
similarly informal limit of a Markov chain related to
the subtree prune and regraft tree (SPR) rearrangements
from phylogenetics.",

and let $ S^* = \sup_{1 \leq n \leq \infty } S_n$
(which is finite a.s.). We construct upper and lower
bounds for $ s_y$ and $ s_y^*$, the upper $ 1 / y$-th
quantile of $ S_y$ and $ S^*$, respectively. Our
approximations rely on an explicitly computable
quantity $ \underline q_y$ for which we prove that\par

\underline q_{2y} \quad \text { and } \quad \frac 1 2
\underline q_{ (y / 4) (1 + \sqrt { 1 - 8 / y})} < s_y
< 2 \underline q_{2y}. $$
The RHS's hold for $ y \geq 2$ and the LHS's for $ y
\geq 94$ and $ y \geq 97$, respectively. Although our
results are derived primarily for symmetric random
variables, they apply to non-negative variates and
extend to an absolute value of a sum of independent but
otherwise arbitrary random variables.",

walk conditioned to come back to the origin after $L$
steps, $ L \in 2 \mathbb {N}$. In the {\em pinning
model} each path $ \eta $ has a weight $
\lambda^{N(\eta)}$, where $ \lambda > 0$ and $ N(\eta)$
is the number of zeros in $ \eta $. When the paths are
constrained to be non-negative, the polymer is said to
satisfy a hard-wall constraint. Such models are well
known to undergo a localization/delocalization
transition as the pinning strength $ \lambda $ is
varied. In this paper we study a natural ``spin flip''
dynamics for associated to these models and derive
several estimates on its spectral gap and mixing time.
In particular, for the system with the wall we prove
that relaxation to equilibrium is always at least as
fast as in the free case (i.e., $ \lambda = 1$ without
the wall), where the gap and the mixing time are known
to scale as $ L^{-2}$ and $ L^2 \log L$, respectively.
This improves considerably over previously known
results. For the system without the wall we show that
the equilibrium phase transition has a clear dynamical
manifestation: for $ \lambda \geq 1$ relaxation is
again at least as fast as the diffusive free case, but
in the strictly delocalized phase ($ \lambda < 1$) the
gap is shown to be $ O(L^{-5 / 2})$, up to logarithmic
corrections. As an application of our bounds, we prove
stretched exponential relaxation of local functions in
the localized regime.",

abstract = "Using the LePage representation, a symmetric
alpha-stable random element in Banach space B with
alpha from (0, 2) can be represented as a sum of points
of a Poisson process in B. This point process is
union-stable, i.e., the union of its two independent
copies coincides in distribution with the rescaled
original point process. This shows that the classical
definition of stable random elements is closely related
to the union-stability property of point processes.
These concepts make sense in any convex cone, i.e., in
a semigroup equipped with multiplication by numbers,
and lead to a construction of stable laws in general
cones by means of the LePage series. We prove that
random samples (or binomial point processes) in rather
general cones converge in distribution in the vague
topology to the union-stable Poisson point process.
This convergence holds also in a stronger topology,
which implies that the sums of points converge in
distribution to the sum of points of the union-stable
point process. Since the latter corresponds to a stable
law, this yields a limit theorem for normalised sums of
random elements with alpha-stable limit for alpha from
(0, 1). By using the technique of harmonic analysis on
semigroups we characterise distributions of
alpha-stable random elements and show how possible
values of the characteristic exponent alpha relate to
the properties of the semigroup and the corresponding
scaling operation, in particular, their distributivity
properties. It is shown that several conditions imply
that a stable random element admits the LePage
representation. The approach developed in the paper not
only makes it possible to handle stable distributions
in rather general cones (like spaces of sets or
measures), but also provides an alternative way to
prove classical limit theorems and deduce the LePage
representation for strictly stable random vectors in

phase transition from a linear regime to a sublinear
regime at time $ n / 2 $. Here, we study the examples
of random 3-regular graphs, random adjacent
transpositions, and riffle shuffles. In the case of a
random 3-regular graph, there is a phase transition
where the speed changes from 1/3 to 0 at time $ 3 l o
g_2 n $. A similar result is proved for riffle
shuffles, where the speed changes from 1 to 0 at time $
l o g_2 n $. Both these changes occur when a distance
equal to the average diameter of the graph is reached.
However in the case of random adjacent transpositions,
the behavior is more complex. We find that there is no
phase transition, even though the distance has
different scalings in three different regimes.",

abstract = "We study Mandelbrot's percolation process in dimension
$ d \geq 2 $. The process generates random fractal sets
by an iterative procedure which starts by dividing the
unit cube $ [0, 1]^d $ in $ N^d $ subcubes, and
independently retaining or discarding each subcube with
probability $p$ or $ 1 - p$ respectively. This step is
then repeated within the retained subcubes at all
scales. As $p$ is varied, there is a percolation phase
transition in terms of paths for all $ d \geq 2$, and
in terms of $ (d - 1)$-dimensional ``sheets'' for all $
d \geq 3$.\par
For any $ d \geq 2$, we consider the random fractal set
produced at the path-percolation critical value $
p_c(N, d)$, and show that the probability that it
contains a path connecting two opposite faces of the
cube $ [0, 1]^d$ tends to one as $ N \to \infty $. As
an immediate consequence, we obtain that the above
probability has a discontinuity, as a function of $p$,
at $ p_c(N, d)$ for all $N$ sufficiently large. This
had previously been proved only for $ d = 2$ (for any $
N \geq 2$). For $ d \geq 3$, we prove analogous results
for sheet-percolation.\par
In dimension two, Chayes and Chayes proved that $
p_c(N, 2)$ converges, as $ N \to \infty $, to the
critical density $ p_c$ of site percolation on the
square lattice. Assuming the existence of the
correlation length exponent $ \nu $ for site
percolation on the square lattice, we establish the
speed of convergence up to a logarithmic factor. In
particular, our results imply that $ p_c(N, 2) - p_c =
(\frac {1}{N})^{1 / \nu + o(1)}$ as $ N \to \infty $,

selective sweep) emerges at the neutral locus. The
classical model assumes that fixation of the beneficial
allele occurs from a single copy of this allele that
arises by mutation. However, recent theory (Pennings
and Hermisson, 2006a, b) has shown that recurrent
beneficial mutation at biologically realistic rates can
lead to markedly different polymorphism patterns,
so-called soft selective sweeps. We extend an approach
that has recently been developed for the classical
hitchhiking model (Schweinsberg and Durrett, 2005;
Etheridge et al., 2006) to study the recurrent mutation
scenario. We show that the genealogy at the neutral
locus can be approximated (to leading orders in the
selection strength) by a marked Yule process with
immigration. Using this formalism, we derive an
improved analytical approximation for the expected
heterozygosity at the neutral locus at the time of
fixation of the beneficial allele.",

systems are those for which the law of $ (X, Q)$ is
invariant under the evolution up to translation of $X$.
It was conjectured by Aizenman and co-authors that the
matrix $Q$ of robustly quasi-stationary systems must
exhibit a hierarchical structure. This was established
recently, up to a natural decomposition of the system,
whenever the set $ S_Q$ of values assumed by $ q_{ij}$
is finite. In this paper, we study the general case
where $ S_Q$ may be infinite. Using the past increments
of the evolution, we show that the law of robustly
quasi-stationary systems must obey the
Ghirlanda--Guerra identities, which first appear in the
study of spin glass models. This provides strong
evidence that the above conjecture also holds in the
general case. In addition, it yields an alternative

the genealogy can be described in terms of the

extended collecting phases that are dominated by global
processes. When extinction and recolonization events
are local, the genealogy is described by Kingman's
coalescent, and the scattering phase influences only
the overall rate of the process. In contrast, if the
demes left vacant by a mass extinction event are
recolonized by individuals emerging from a small number
of demes, then the limiting genealogy is a coalescent
process with simultaneous multiple mergers (a $ \Xi
$-coalescent). In this case, the details of the
within-deme population dynamics influence not only the
overall rate of the coalescent process, but also the
statistics of the complex mergers that can occur within

convergence. We show that the convergence of the full

most symmetric in a variety of senses. Somewhat similar
representations - of any probability distribution as
the mixture of two-point distributions with the same
skewness coefficient (but possibly with different
means) - go back to Kolmogorov; very recently, Aizenman
et al. further developed such representations and
applied them to (anti-)concentration inequalities for
functions of independent random variables and to
spectral localization for random Schroedinger
operators. One kind of application given in the present

abstract = "We consider competing particle systems in $ \mathbb
{R}^d $, i.e., random locally finite upper bounded
configurations of points in $ \mathbb {R}^d $ evolving
in discrete time steps. In each step i.i.d. increments
are added to the particles independently of the initial
configuration and the previous steps. Ruzmaikina and
Aizenman characterized quasi-stationary measures of
such an evolution, i.e., point processes for which the
joint distribution of the gaps between the particles is
invariant under the evolution, in case $ d = 1 $ and
restricting to increments having a density and an
everywhere finite moment generating function. We prove
corresponding versions of their theorem in dimension $
d = 1 $ for heavy-tailed increments in the domain of
attraction of a stable law and in dimension $ d \geq 1
$ for lattice type increments with an everywhere finite
moment generating function. In all cases we only assume
that under the initial configuration no two particles
are located at the same point. In addition, we analyze
the attractivity of quasi-stationary Poisson point
processes in the space of all Poisson point processes
with almost surely infinite, locally finite and upper
bounded configurations.",

chains constructed by parallel and simulated tempering,
and provide a set of sufficient conditions for torpid
mixing of both techniques. Combined with the results of
Woodard, Schmidler and Huber (2009), these results
yield a two-sided bound on the spectral gap of these
algorithms. We identify a persistence property of the
target distribution, and show that it can lead
unexpectedly to slow mixing that commonly used
convergence diagnostics will fail to detect. For a
multimodal distribution, the persistence is a measure
of how ``spiky'', or tall and narrow, one peak is
relative to the other peaks of the distribution. We
show that this persistence phenomenon can be used to
explain the torpid mixing of parallel and simulated
tempering on the ferromagnetic mean-field Potts model
shown previously. We also illustrate how it causes
torpid mixing of tempering on a mixture of normal
distributions with unequal covariances in $ R^M $, a
previously unknown result with relevance to statistical
inference problems. More generally, anytime a
multimodal distribution includes both very narrow and
very wide peaks of comparable probability mass,
parallel and simulated tempering are shown to mix
slowly.",

a degenerate random variable whenever the subordinator

associated subordinator has Laplace exponent that
varies regularly at $ 0.$ Moreover, we show that $

\alpha, $ a.s. and provide an integral test for the
upper functions of $ \{ \log (X(t)), t \geq 0 \} $.
Furthermore, results concerning the rate of growth of
the random clock appearing in Lamperti's transformation
are obtained. In particular, these allow us to
establish estimates for the left tail of some
exponential functionals of subordinators. Finally, some
of the implications of these results in the theory of
