Laine and Langley is closely related to confluent
hypergeometric functions, Bessel functions and Bessel
polynomials. As a result, we give a complete
characterization of the zero-distribution in the sense
of Nevanlinna theory of the solutions for two classes
of the ODEs. Our approach uses special functions and
their asymptotics. New results concerning finiteness of
the number of zeros (finite-zeros) problem of Bessel
and Coulomb wave functions with respect to the
parameters are also obtained as a consequence. We
demonstrate that the problem for the remaining class of
ODEs not covered by the above {``special function
approach''} can be described by a classical Heine
problem for differential equations that admit
polynomial solutions.",

Consider the rank of the multiplicative subgroup of

We say $q$ is of $full rank$ if either the rank is $d -
1$ and $q$ has norm $pm 1$, or the rank is $d$. In this

where $q$ is an algebraic integer of full rank. The
special cases of when $q$ is a Pisot number and when
$q$ is a Pisot-cyclotomic number are also studied.
There are four main results. (1) If $q$ is an algebraic
integer of full rank and $n$ is a fixed positive
integer, then there are only finitely many $m$ such
that disc $({\mathbb Z}[q$^m$ ]) =$ disc $({\mathbb
Z}[q$^n$ ])$. (2) If $q$ and $r$ are algebraic integers
of degree $d$ of full rank and ${\mathbb Z][q$^n$ ] =
{\mathbb Z}[r$^n$ ]$ for infinitely many $n$, then
either $q = \omega r$^'$$ or $q =$ Norm $(r)$^{{2/d}}$
\omega/r$^{', where r '}$$ is some conjugate of $r$ and
$\omega$ is some root of unity. (3) Let $r$ be an
algebraic integer of degree at most 3. Then there are
at most 40 Pisot numbers $q$ such that ${\mathbb Z}[q]
= {\mathbb Z}[r]$. (4) There are only finitely many
Pisot-cyclotomic numbers of any fixed order.??}",

G) to the elementary theories of the direct factors of
G (to the elementary theory of coordinate groups of
irreducible algebraic sets). Then we establish normal
forms for quantifier-free formulas over a non-abelian
directly indecomposable partially commutative group H.
Analogously to the case of free groups, we introduce
the notion of a generalised equation and prove that the
positive theory of H has quantifier elimination and
that arbitrary first-order formulas lift from H to H*
F, where F is a free group of finite rank. As a

algebraic structures and the noncommutative deformation
theory of modules over algebras due to Laudal. In the
first part of the paper, we describe a noncommutative
deformation functor for presheaves of modules on a
small category and an obstruction theory for this
functor in terms of global Hochschild cohomology. An
important feature of this obstruction theory is that it
can be computed in concrete terms in many interesting
cases. In the last part of the paper, we describe a
noncommutative deformation functor for quasi-coherent
sheaves of modules on a ringed space $(X,
\mathcal{A})$. We show that for any good
$\mathcal{A}$-affine open cover $\mathsf{U}$ of $X$,
the forgetful functor $\mathsf{QCoh}\mathcal{A} \to
\mathsf{PreSh}(\mathsf{U}, \mathcal{A})$ induces an
isomorphism of noncommutative deformation functors.
\emph{Applications.} We consider noncommutative
deformations of quasi-coherent $\mathcal{A}$-modules on
$X$ when $(X, \mathcal{A}) = (X, \mathcal{O}_X)$ is a
scheme or $(X, \mathcal{A}) = (X, \mathcal{D})$ is a
D-scheme in the sense of Beilinson and Bernstein. In
these cases, we may use any open affine cover of $X$
closed under finite intersections to compute
noncommutative deformations in concrete terms using
presheaf methods. We compute the noncommutative
deformations of the left $\sh D$_X$ $-module
$\mathcal{D}$_X$ $ when $X$ is an elliptic curve as an
example.",

are unitary, to show the irreducibility of $\pi$, it
suffices to show that ${\rm dim}_C {\rm
Hom}_{G^{\texttt{~}}}(\pi, \pi) = 1$. We will
accomplish this by examining the poles of certain
intertwining operators associated to simple roots. Then
some results of Shahidi and Ban decompose arbitrary
intertwining operators into a composition of operators
corresponding to the simple roots of
$G^{\texttt{~}}_2$. We will then be able to show that

X {\subset} Y be the zero set of a section {\sigma}

relationship between the functor that deforms the pair
( $F$,{\sigma}) and the two functors that deform $F$ on
Y, and X in Y, respectively. By imposing some
conditions on two forgetful maps between the functors,
we prove that the scheme structure of e.g., the moduli
scheme M $_Y$ (P) of stable sheaves on a threefold Y at
( $F$), and the scheme structure at (X) of the Hilbert
scheme of curves on Y become closely related. Using
this relationship, we get criteria for the dimension

assuming Ext$^2$ ( $F$, $F$) = 0. For reflexive sheaves
on Y= {\bf P}$^3$ whose deficiency module M = H$_*^1$ (
$F$) satisfies$_0$ Ext$^2$ (M,M) = 0 ( e.g., of
diameter at most 2), we get necessary and sufficient
conditions of unobstructedness that coincide in the

equivalent to the vanishing of certain graded Betti

component of $M_P^3(P)$ containing a reflexive sheaf of

compute its dimension. We also determine a good lower

values of all rank 1 elliptic curves is logarithmically
larger than the rank 1 curves in the positive rank
family. Furthermore, as arithmetical applications, we
make a conjecture on the distribution of a$_p$ 's

decomposition, with the coefficients depending on a
fixed parameter {\beta} > 0. On its support I$_0$

expansions of the coordinates of x. In particular,
f=f$_{{\beta}}$ {\in} Q$_{{\alpha}}$ ( {\bf R}$^n$) if

f is a self-affine function. It is continuous almost
everywhere and discontinuous at all dyadic points
inside I$_0$. In addition, it is not monotone along any
coordinate direction in any small cube. When the
parameter {\beta} {\in} (0, 1), f is onto from $I_0$ to
$[-1/(1 - 2^{-\beta}), 1 / (1 - 2^{-\beta})]$, and the

satisfied by asymptotically flat manifolds. We also

F-group, the complex vector space $H$ (G) of compactly

natural convolution product that makes it into a {\bf
C} -algebra (without an identity) called the Hecke
algebra. The Hecke algebra is a partial analogue for
p-adic groups of the enveloping algebra of a Lie group.
However, $H$ (G) has drawbacks such as the lack of an
identity element, and the process G {\rightarrow} $H$
(G) is not a functor. Bernstein introduced an
enlargement $H$ {\wedge} (G) of $H$ (G). The algebra
$H$ {\wedge} (G) consists of the distributions that are
left essentially compact. We show that the process G

G {\rightarrow}H is a morphism of p-adic groups, let
F({\tau}) : $H$ {\wedge} (G) {\rightarrow} $H$ {\wedge}

show that F({\tau}) maps G-invariant distributions on
$G$ to N$_G$ ( {\bf m} )-invariant distributions on

be dual to the intertwining operators, indexed by
elements $u$ of the Weyl group $W$. On the other hand,
there is a natural basis $\psi_u$, and one seeks to
find the transition matrices between the two bases.
Thus, let $f_u = \sum_v \tilde{m} (u, v) \psi_v$ and
$\psi_u = \sum_v m (u, v) f_v$. Using the Iwahori-Hecke
algebra we prove that if a combinatorial condition is
satisfied, then $m (u, v) = \prod_{\alpha} \frac{1 -
q^{- 1} \mathbf{z}^{\alpha}}{1 -\mathbf{z}^{\alpha}}$,

v)$ of positive coroots $\alpha \in \hat{\Phi}$ (the
dual root system of $G$) such that $u \leqslant v
r_\alpha < v$ with $r_{\alpha}$ the reflection

conjecturally always satisfied if $G$ is simply-laced
and the Kazhdan--Lusztig polynomial $P_{w_0 v, w_0 u} =
1$ with $w_0$ the long Weyl group element. There is a
similar formula for $\tilde{m}$ conjecturally satisfied
if $P_{u, v} = 1$. This leads to various combinatorial

perturbing the Euclidean metric by a translation,
$F_b=\alpha+\beta$, where $\alpha$ is the Euclidean
metric and $\beta$ is a $1$-form with norm $b$, $0\leq
b\lt 1$. We introduce the concept of a hypersurface
with constant mean curvature in the direction of a
unitary normal vector field. We obtain the ordinary
differential equation that characterizes the rotational
surfaces $(V^3,F_b)$ of constant mean curvature (cmc)
in the direction of a unitary normal vector field.
These equations reduce to the classical equation of the
rotational cmc surfaces in Euclidean space, when $b=0$.
It also reduces to the equation that characterizes the
minimal rotational surfaces in $(V^3,F_b)$ when $H=0$,
obtained by M. Souza and K. Tenenblat. Although the
differential equation depends on the choice of the
normal direction, we show that both equations determine
the same rotational surface, up to a reflection. We
also show that the round cylinders are cmc surfaces in
the direction of the unitary normal field. They are
generated by the constant solution of the differential
equation. By considering the equation as a nonlinear
dynamical system, we provide a qualitative analysis,
for $0\lt b\lt \frac{\sqrt{3}}{3}$. Using the concept
of stability and considering the linearization around
the single equilibrium point (the constant solution),
we verify that the solutions are locally asymptotically
stable spirals. This is proved by constructing a
Lyapunov function for the dynamical system and by
determining the basin of stability of the equilibrium
point. The surfaces of rotation generated by such
solutions tend asymptotically to one end of the
cylinder.",

harmonic oscillator (Hermite operator) has recently
been treated by Bongioanni and Torrea by using a
straightforward approach of kernel estimates. Here
these results are applied in certain Laguerre settings.
The procedure is fairly direct for Laguerre function
expansions of Hermite type, due to some monotonicity
properties of the kernels involved. The case of
Laguerre function expansions of convolution type is
less straightforward. For half-integer type indices
$\alpha$ we transfer the desired results from the
Hermite setting and then apply an interpolation
argument based on a device we call the convexity
principle to cover the continuous range of $\alpha \in
[-1/2, \infty)^d$. Finally, we investigate negative
powers of the Dunkl harmonic oscillator in the context
of a finite reflection group acting on $\mathbb{R}^d$
and isomorphic to $\mathbb Z^d_2$. The two weight
$L^p-L^q$ estimates we obtain in this setting are
essentially consequences of those for Laguerre function
expansions of convolution type.",

conjugating some power of the previous one to another

fairly general conditions, the group turns out to be
finite and solvable of derived length $\leq 3$. We
obtain a lot of information about finite quotients,

resolution of singularities in $\mathcal C$, e.g., the
real analytic class, then $f$ admits a lift of the same

has an exponential singularity, there is a
$\theta$-function $T_\zeta(q)$ with

``universal'' mock $\theta$-function. Modular
transformations of $H$ give rise to the functions $K$,
$K_1$, $K_2$. The functions $K$ and $K_1$ appear in

formulas with some strong symmetry. The new proof is
shorter and simpler compared to the original one by Xu,
and moreover gives a general interpretation of the
analytically-written conditions of Xu's theorems.
Second, we extend a theorem by Neumaier and Seidel
(1988) on Euclidean designs to invariant Euclidean
designs, and thereby classify tight Euclidean designs
obtained from unions of the orbits of the corner
vectors. This result generalizes a theorem of Bajnok

investigate the Kadison-Singer conjecture, proving its
equivalence to an apparently quite weak paving
conjecture and the existence of unique maximal centred
extensions of projections coming from ultrafilters on
the natural numbers. We then prove that Reid's positive
answer to this for q-points in fact also holds for
rapid p-points, and that maximal centred filters are
obtained in this case. We then show that consistently
such maximal centred filters do not exist at all
meaning that, for every pure state on the Calkin
algebra, there exists a pair of projections on which
the state is 1, even though the state is bounded
strictly below 1 for projections below this pair.
Lastly we investigate towers, using cardinal invariant
equalities to construct towers on the natural numbers
that do and do not remain towers when canonically
embedded into the Calkin algebra. Finally we show that
consistently all towers on the natural numbers remain
towers under this embedding.",

give a full characterization of extremely projective

so-called homogeneous modules. We consider two cases,
`non-complete' and `complete', and the respective
answers turn out to be essentially different. In
particular, all Banach non-degenerate homogeneous
modules, consisting of sequences, are extremely
projective within the category of Banach non-degenerate
homogeneous modules. However, neither of them, provided
it is infinite-dimensional, is extremely projective
within the category of all normed non-degenerate

a comparison principle for DOT along characteristic
curves under bounds on COT. In particular, this gives
estimates on lengths of characteristic curves assuming
COT is bounded below by a positive constant. We show
that surfaces with constant COT exist and we classify
all graphs in the Heisenberg group with vanishing COT.
This is accomplished by showing that the equation for
graphs with zero COT can be decomposed into two first
order PDEs, one of which is the backward invisicid
Burgers' equation. Finally we show that the p-minimal
graph equation in the Heisenberg group also has such a
decomposition. Moreover, we can use this decomposition
to write down an explicit formula of a solution near a

theory of semigroup algebras. When $ \delta = 1 $, we
obtain the matching complex, for which it is known that
there is $3$-torsion in degree $d$ of the homology

This paper establishes similar bounds for $ \delta \ge
2 $. Specifically, there is $3$-torsion in degree $d$
whenever $ \frac {(3 \delta - 1)n - 86} \le d \le \frac
{\delta (n - 1) - 42} $. The procedure for detecting
torsion is to construct an explicit cycle $z$ that is
easily seen to have the property that $ 3 z $ is a
boundary. Defining a homomorphism that sends $z$ to a
non-boundary element in the chain complex of a certain
matching complex, we obtain that $z$ itself is a
non-boundary. In particular, the homology class of $z$

to describe combinatorial properties of the classical

are obtained by an enumeration of connected matchings,
the weight being now an evaluation of the Tutte

symmetric functions and hypergeometric series. We show
that the underlying combinatorics is explained through

show that ``quantum point-masses{\SGMLquot} can be
identified with several other locally compact groups

\mathbb {G} $. This assignment preserves compactness as
well as discreteness (hence also finiteness), and for
large classes of quantum groups, amenability. We
calculate this invariant for some of the most
well-known examples of non-classical quantum groups.
Also, we show that several structural properties of $

important family of homeomorphisms of the tori $

Using the Pimsner-Voiculescu theorem, we prove that
given $n$, the $K$-groups of those crossed products,
whose corresponding $ n \times n $ integer matrices are
unipotent of maximal degree, always have the same rank
$ a_n $. We show using the theory developed here that a
claim made in the literature about the torsion
subgroups of these $K$-groups is false. Using the
representation theory of the simple Lie algebra $ \frak
{sl}(2, \mathbb {C}) $, we show that, remarkably, $ a_n
$ has a combinatorial significance. For example, every
$ a_{2n + 1} $ is just the number of ways that $0$ can
be represented as a sum of integers between $ - n $ and
$n$ (with no repetitions). By adapting an argument of
van Lint (in which he answered a question of
Erd{\SGMLquot}os), a simple, explicit formula for the
asymptotic behavior of the sequence $ \{ a_n \} $ is
given. Finally, we describe the order structure of the
$ K_0 $-groups of an important class of Furstenberg

answer. We first study a component of this obstruction,
which gives the condition that the leafwise cohomology

a symplectic fibre bundle over a complex base. We then
show how to compute the full obstruction via a spectral
sequence. We give various concrete necessary and
sufficient conditions for the vanishing of the
obstruction. Throughout, we give examples to test the
sharpness of these conditions, including a symplectic
fibre bundle over a complex base which does not come

generalized complex structure which is very unlike a
symplectic fibre bundle, i.e., for which nearby leaves

involves the structure of $ \operatorname {End}(B) $,
isogenies between the Galois conjugates of $B$, and a
Galois cohomology class attached to $ B / K $. We call
the varieties having this property strongly modular.
The last section is devoted to the study of a family of
abelian surfaces with quaternionic multiplication. As
an illustration of the ways in which the general
results of the paper can be applied we prove the strong
modularity of some particular abelian surfaces
belonging to that family, and we show how to find

introduced as dualizations of Frobenius algebras. We
previously showed that they admit left-right symmetric
characterizations analogue to those of Frobenius
algebras. We consider the more general
quasi-co-Frobenius (QcF) coalgebras; the first main
result in this paper is that these also admit symmetric
characterizations: a coalgebra is QcF if it is weakly
isomorphic to its (left, or right) rational dual $ R a
t(C^*) $, in the sense that certain coproduct or
product powers of these objects are isomorphic.
Fundamental results of Hopf algebras, such as the
equivalent characterizations of Hopf algebras with
nonzero integrals as left (or right) co-Frobenius, QcF,
semiperfect or with nonzero rational dual, as well as
the uniqueness of integrals and a short proof of the
bijectivity of the antipode for such Hopf algebras all
follow as a consequence of these results. This gives a
purely representation theoretic approach to many of the
basic fundamental results in the theory of Hopf
algebras. Furthermore, we introduce a general concept
of Frobenius algebra, which makes sense for infinite
dimensional and for topological algebras, and
specializes to the classical notion in the finite case.
This will be a topological algebra $A$ that is
isomorphic to its complete topological dual $ A^\vee $.
We show that $A$ is a (quasi)Frobenius algebra if and
only if $A$ is the dual $ C^* $ of a
(quasi)co-Frobenius coalgebra $C$. We give many
examples of co-Frobenius coalgebras and Hopf algebras
connected to category theory, homological algebra and
the newer q-homological algebra, topology or graph
theory, showing the importance of the concept.",

states that if one factor is connected and the other is
free as a monoid, their Hadamard product is free (and
connected). The second provides an explicit basis for
the Hadamard product when both factors are free. The
first main result is obtained by showing the existence
of a one-parameter deformation of the comonoid
structure and appealing to a rigidity result of Loday
and Ronco that applies when the parameter is set to
zero. To obtain the second result, we introduce an
operation on species that is intertwined by the free
monoid functor with the Hadamard product. As an
application of the first result, we deduce that the

One is obtained from the Euclidean Fourier transform,

proving the existence of no rational points on a coarse
moduli space $X$ of abelian varieties over a given
number field $K$, in cases where the moduli problem is
not fine and points in $ X(K)$ may not be represented
by an abelian variety (with additional structure)
admitting a model over the field $K$. This is typically
the case when the abelian varieties that are being
classified have even dimension. The main idea, inspired
on the work of Ellenberg and Skinner on the modularity
of $ \mathbb {Q}$-curves, is that to a point $ P = [A]
\in X(K)$ represented by an abelian variety $ A / \bar
K$ one may still attach a Galois representation of $
\operatorname {Gal}(\bar K / K)$ with values in the
quotient group $ \operatorname {GL}(T_\ell (A)) /
\operatorname {Aut}(A)$, provided $ \operatorname
{Aut}(A)$ lies in the centre of $ \operatorname
{GL}(T_\ell (A))$. We exemplify our method in the cases
where $X$ is a Shimura curve over an imaginary
quadratic field or an Atkin-Lehner quotient over $

give an explicit formula for a natural map from the set

the analogous set for $ \tilde {G}^*(k)$. If $k$ is

abstract = "A simple finite dimensional module $ V_\lambda $ of a
simple complex algebraic group $G$ is naturally endowed
with a filtration induced by the PBW-filtration of $
U(\mathrm {Lie} \, G)$. The associated graded space $
V_\lambda^a$ is a module for the group $ G^a$, which
can be roughly described as a semi-direct product of a
Borel subgroup of $G$ and a large commutative unipotent
group $ \mathbb {G}_a^M$. In analogy to the flag
variety $ \mathcal {F}_\lambda = G.[v_\lambda] \subset
\mathbb {P}(V_\lambda)$, we call the closure $
\overline {G^a.[v_\lambda]} \subset \mathbb
{P}(V_\lambda^a)$ of the $ G^a$-orbit through the
highest weight line the degenerate flag variety $
\mathcal {F}^a_\lambda $. In general this is a singular
variety, but we conjecture that it has many nice
properties similar to that of Schubert varieties. In
this paper we consider the case of $G$ being the
symplectic group. The symplectic case is important for
the conjecture because it is the first known case where
even for fundamental weights $ \omega $ the varieties $
\mathcal {F}^a_\omega $ differ from $ \mathcal
{F}_\omega $. We give an explicit construction of the
varieties $ S p \mathcal {F}^a_\lambda $ and construct
desingularizations, similar to the Bott-Samelson
resolutions in the classical case. We prove that $ S p
\mathcal {F}^a_\lambda $ are normal locally complete
intersections with terminal and rational singularities.
We also show that these varieties are Frobenius split.
Using the above mentioned results, we prove an analogue
of the Borel--Weil theorem and obtain a $q$-character
formula for the characters of irreducible $ S
p_{2n}$-modules via the Atiyah-Bott-Lefschetz fixed
points formula.",

near the equator as the Euclidean ball. We apply this

eigenvarieties of unitary groups at points
corresponding to tempered non-stable representations

that, except in the case the Galois representation
attached to the automorphic form is a sum of
characters, the eigenvariety is non-smooth at such a
point, and that (under some additional hypotheses) its
tangent space is big enough to account for all the
relevant Selmer group. We also study the local
reducibility locus at those points, proving that in
general, in contrast with the case of the eigencurve,
it is a proper subscheme of the fiber of the
eigenvariety over the weight space.",

subgroup or $X$ is locally of finite $G$-orbit type.
Then the upper multiplicity of the representation of

by restricting $V$ to a certain closed subgroup of the
stability subgroup and taking the maximum of the
multiplicities of the irreducible summands occurring in

when the trivial subgroup is a principal stability
subgroup, the crossed product is a Fell algebra if and
only if every stability subgroup is abelian. A second
corollary is that the $ C^*$-algebra of the motion
group $ \mathbb {R}^n \rtimes \operatorname {SO}(n)$ is
a Fell algebra. This uses the classical branching
theorem for the special orthogonal group $
\operatorname {SO}(n)$ with respect to $ \operatorname

$n$-stacks which are of strongly finite type over the
ring of $p$-adic integers. $p$-adic measure on schemes
can be evaluated by counting points on the reduction of
the scheme modulo $ p^n$. We show that an analogous
construction works in the case of Artin stacks as well
if we count the points using the counting measure
defined by To{\"e}n. As a consequence, we obtain the
result that the Poincar{\'e} and Serre series of such
stacks are rational functions, thus extending Denef's
result for varieties. Finally, using motivic
integration we show that as $p$ varies, the rationality
of the Serre series of an Artin stack defined over the
integers is uniform with respect to $p$.",

place $v$, $ \pi_v$ is equivalent to the local
metaplectic tensor product of $ \pi_{1, v}, \dots,

of $ \pi_i$ are cuspidal (resp. square-integrable
modulo center), then the metaplectic tensor product is
cuspidal (resp. square-integrable modulo center). We
also show that (both locally and globally) the
metaplectic tensor product behaves in the expected way
under the action of a Weyl group element, and show the
compatibility with parabolic inductions.",

image of the critical locus, under iteration of $f$,

graphs, and explore its merit as a notion of
``curvature'' in discrete spaces. An appealing feature
of this discrete version of the so-called $
\Gamma_2$-calculus (of Bakry-{\'E}mery) seems to be
that it is fairly straightforward to compute this
notion of curvature parameter for several specific
graphs of interest -- particularly, abelian groups,
slices of the hypercube, and the symmetric group under
various sets of generators. We further develop this
notion by deriving Buser-type inequalities ({\`a} la
Ledoux), relating functional and isoperimetric
constants associated with a graph. Our derivations
provide a tight bound on the Cheeger constant (i.e.,
the edge-isoperimetric constant) in terms of the
spectral gap, for graphs with nonnegative curvature,
particularly, the class of abelian Cayley graphs -- a
result of independent interest.",

theorem for certain ``Toeplitz'' operators in the same

C^*$-algebra, $A$. We assume a faithful $Z$-valued
trace $ \tau $ on $A$ left invariant under an action $
\alpha : {\mathbf R} \to A u t(A)$ leaving $Z$
pointwise fixed.If $ \delta $ is the infinitesimal
generator of $ \alpha $ and $u$ is invertible in $
\operatorname {dom}(\delta)$ then the ``winding
operator'' of $u$ is $ \frac {1}{2 \pi i} \tau (\delta
(u)u^{-1}) \in Z_{sa}.$ By a careful choice of
representations we extend $ (A, Z, \tau, \alpha)$ to a
von Neumann setting $ (\mathfrak {A}, \mathfrak {Z},
\bar \tau, \bar \alpha)$ where $ \mathfrak {A} =
A^{\prime \prime }$ and $ \mathfrak {Z} = Z^{\prime

and show it is Fredholm in an appropriate sense and the
$ \mathfrak {Z}$-valued index of $ T_u$ is the negative
of the winding operator. In outline the proof follows
the proof of the scalar case done previously by the
authors. The main difficulty is making sense of the
constructions with the scalars replaced by $ \mathfrak
{Z}$ in the von Neumann setting. The construction of
the dual $ \mathfrak {Z}$-trace on $ \mathfrak {A}
\rtimes {\mathbf R}$ required the nontrivial
development of a $ \mathfrak {Z}$-Hilbert Algebra

operators fiber as a ``section'' of Fredholm operators

ingredient is a collection of explicit formulae for the
sequence $ v(\Psi_n)$ of valuations of the division
polynomials. For $P$ of non-singular reduction, such
sequences are already well described in most cases, but
for $P$ of singular reduction, we are led to define a
new class of sequences called \emph{elliptic
troublemaker sequences}, which measure the failure of
the N{\'e}ron local height to be quadratic. As a

already known, so we extend it to the other cases.
Moreover, we prove that a K3 surface $ X_G$ is the
minimal model of the quotient of an Abelian surface by
a group $G$ if and only if a certain configuration of
rational curves is present on $ X_G$. Again this result
was known only in some special cases, in particular if

comparison: If $ \mathcal {A}$ is a simple separable
stable C*-algebra with real rank zero, stable rank one,
and strict comparison of positive elements by traces,
then whether a positive element is a positive linear
combination of projections is determined by the trace

are free analogs of analytic functions in several
complex variables, and are defined in terms of freely
noncommuting variables. A function of $g$ noncommuting
variables is a function on $g$-tuples of square
matrices of all sizes that respects direct sums and
simultaneous conjugation. Examples of such maps include
noncommutative polynomials, noncommutative rational
functions and convergent noncommutative power series.
In sharp contrast to the existing literature in free
analysis, this article investigates free maps
\emph{with involution} -- free analogs of real analytic
functions. To get a grip on these, techniques and tools
from invariant theory are developed and applied to free
analysis. Here is a sample of the results obtained. A
characterization of polynomial free maps via properties
of their finite-dimensional slices is presented and
then used to establish power series expansions for
analytic free maps about scalar and non-scalar points;
the latter are series of generalized polynomials for
which an invariant-theoretic characterization is given.
Furthermore, an inverse and implicit function theorem
for free maps with involution is obtained. Finally,
with a selection of carefully chosen examples it is
shown that free maps with involution do not exhibit
strong rigidity properties enjoyed by their
involution-free counterparts.",

algebras $ \mathfrak {k} $, also called affinisations
of $ \mathfrak {k} $. They possess a root space
decomposition whose corresponding root system is a
locally affine root system of one of the $7$ families $
A_J^{(1)}$, $ B_J^{(1)}$, $ C_J^{(1)}$, $ D_J^{(1)}$, $
B_J^{(2)}$, $ C_J^{(2)}$ and $ B C_J^{(2)}$ for some
infinite set $J$. To each of these types corresponds a
``{minimal"} affinisation of some simple Hilbert-Lie
algebra $ \mathfrak {k}$, which we call standard. In
this paper, we give for each affinisation $ \mathfrak
{g}$ of a simple Hilbert-Lie algebra $ \mathfrak {k}$
an explicit isomorphism from $ \mathfrak {g}$ to one of
the standard affinisations of $ \mathfrak {k}$. The
existence of such an isomorphism could also be derived
from the classification of locally affine root systems,
but for representation theoretic purposes it is crucial
to obtain it explicitly as a deformation between two
twists which is compatible with the root
decompositions. We illustrate this by applying our
isomorphism theorem to the study of positive energy
highest weight representations of $ \mathfrak {g}$. In
subsequent work, the present paper will be used to
obtain a complete classification of the positive energy
highest weight representations of affinisations of $

1), \dots $ are algebraically independent over $
\mathbb {C}(x) $. More generally, for a linear
differential or difference equation, it is an important
problem to find all algebraic dependencies among a
non-zero solution $y$ and particular transformations of
$y$, such as derivatives of $y$ with respect to
parameters, shifts of the arguments, rescaling, etc. In
the present paper, we develop a theory of Tannakian
categories with semigroup actions, which will be used
to attack such questions in full generality, as each
linear differential equation gives rise to a Tannakian
category. Deligne studied actions of braid groups on
categories and obtained a finite collection of axioms
that characterizes such actions to apply it to various
geometric constructions. In this paper, we find a
finite set of axioms that characterizes actions of
semigroups that are finite free products of semigroups
of the form $ \mathbb {N}^n \times \mathbb {Z} / {n_1}
\mathbb {Z} \times \cdots \times \mathbb {Z} / {n_r}

of manifolds with well-behaved torus actions (simply,
toric spaces) are classified by pairs of simplicial
complexes and (non-singular) characteristic maps. The
authors in their previous paper provided a new way to
find all characteristic maps on a simplicial complex $
K(J) $ obtainable by a sequence of wedgings from $K$.
The main idea was that characteristic maps on $K$
theoretically determine all possible characteristic
maps on a wedge of $K$. In this work, we further
develop our previous work for classification of toric
spaces. For a star-shaped simplicial sphere $K$ of
dimension $ n - 1$ with $m$ vertices, the Picard number
$ \operatorname {Pic}(K)$ of $K$ is $ m - n$. We refer
to $K$ as a seed if $K$ cannot be obtained by wedgings.
First, we show that, for a fixed positive integer $
\ell $, there are at most finitely many seeds of Picard
number $ \ell $ supporting characteristic maps. As a
corollary, the conjecture proposed by V.V. Batyrev in
1991 is solved affirmatively. Second, we investigate a
systematic method to find all characteristic maps on $
K(J)$ using combinatorial objects called (realizable)
puzzles that only depend on a seed $K$. These two facts
lead to a practical way to classify the toric spaces of
fixed Picard number.",

polynomials that provide a good approximation to a
function that is constant on the complex unit circle,
and in particular have small $ L^q $ norm on the
complex unit circle. We consider the Fekete polynomials
\[ f_p(z)=\sum_{j=1}^{p-1}(j\,|\,p)\,z^j, \] where $p$
is an odd prime and $ (\, \cdot \, | \, p)$ is the
Legendre symbol (so that $ z^{-1}f_p(z)$ is a
Littlewood polynomial). We give explicit and recursive
formulas for the limit of the ratio of $ L^q$ and $
L^2$ norm of $ f_p$ when $q$ is an even positive
integer and $ p \to \infty $. To our knowledge, these
are the first results that give these limiting values
for specific sequences of nontrivial Littlewood
polynomials and infinitely many $q$. Similar results
are given for polynomials obtained by cyclically
permuting the coefficients of Fekete polynomials and
for Littlewood polynomials whose coefficients are
obtained from additive characters of finite fields.

results for C*-algebras with the weak ideal property or
topological dimension zero, and some results for
C*-algebras with related properties. Some of the more
important results include: $ \bullet $ The weak ideal
property implies topological dimension zero. $ \bullet
$ For a separable C*-algebra~$A$, topological dimension
zero is equivalent to $ {\operatorname {RR}} ({\mathcal
{O}}_2 \otimes A) = 0$, to $ D \otimes A$ having the
ideal property for some (or any) Kirchberg algebra~$D$,
and to $A$ being residually hereditarily in the class
of all C*-algebras $B$ such that $ {\mathcal
{O}}_{\infty } \otimes B$ contains a nonzero
projection. $ \bullet $ Extending the known result for
$ {\mathbb {Z}}_2$, the classes of C*-algebras with
residual (SP), which are residually hereditarily
(properly) infinite, or which are purely infinite and
have the ideal property, are closed under crossed
products by arbitrary actions of abelian $2$-groups. $
\bullet $ If $A$ and $B$ are separable, one of them is
exact, $A$ has the ideal property, and $B$ has the weak
ideal property, then $ A \otimes_{\mathrm {min}} B$ has
the weak ideal property. $ \bullet $ If $X$ is a
totally disconnected locally compact Hausdorff space
and $A$ is a $ C_0 (X)$-algebra all of whose fibers
have one of the weak ideal property, topological
dimension zero, residual (SP), or the combination of
pure infiniteness and the ideal property, then $A$ also
has the corresponding property (for topological
dimension zero, provided $A$ is separable). $ \bullet $
Topological dimension zero, the weak ideal property,
and the ideal property are all equivalent for a
substantial class of separable C*-algebras including
all separable locally AH~algebras. $ \bullet $ The weak
ideal property does not imply the ideal property for
separable $Z$-stable C*-algebras. We give other related
results, as well as counterexamples to several other

earlier work, we do not assume that the graphs satisfy
the standard condition (K), so that the graph $
C^*$-algebras may come with uncountably many ideals. We
find that in this generality, stable isomorphism of
graph $ C^*$-algebras does not coincide with the
geometric notion of Cuntz move equivalence. However,
adding a modest condition on the graphs, the two
notions are proved to be mutually equivalent and
equivalent to the $ C^*$-algebras having isomorphic
$K$-theories. This proves in turn that under this
condition, the graph $ C^*$-algebras are in fact
classifiable by $K$-theory, providing in particular
complete classification when the $ C^*$-algebras in
question are either of real rank zero or type
I/postliminal. The key ingredient in obtaining these
results is a characterization of Cuntz move equivalence
using the adjacency matrices of the graphs. Our results
are applied to discuss the classification problem for
the quantum lens spaces defined by Hong and

classes of self-maps on metric spaces $ \langle X, d
\rangle $ with the local and pointwise (a.k.a. local
radial) contraction properties. Each of those classes
appeared previously in the literature in the context of
fixed point theorems. We begin with presenting an
overview of these fixed point results, including
concise self contained sketches of their proofs. Then,
we proceed with a discussion of the relations among the
ten classes of self-maps with domains $ \langle X, d
\rangle $ having various topological properties which
often appear in the theory of fixed point theorems:
completeness, compactness, (path) connectedness,
rectifiable path connectedness, and $d$-convexity. The
bulk of the results presented in this part consists of
examples of maps that show non-reversibility of the
previously established inclusions between theses
classes. Among these examples, the most striking is a
differentiable auto-homeomorphism $f$ of a compact
perfect subset $X$ of $ \mathbb R$ with $ f' \equiv 0$,
which constitutes also a minimal dynamical system. We
finish with discussing a few remaining open problems on
weather the maps with specific pointwise contraction
properties must have the fixed points.",

S_j(x) = \varrho x + d_j $ and probabilities $ p_j \gt
0 $ with $ \sum p_j = 1 $. We are interested in the
self-similar measure $ \mu = \sum p_j \mu \circ
S_j^{-1} $, of finite type. In this paper we study the
multi-fractal analysis of such measures, extending the
theory to measures arising from non-regular
probabilities and whose support is not necessarily an
interval. Under some mild technical assumptions, we
prove that there exists a subset of supp$ \mu $ of full
$ \mu $ and Hausdorff measure, called the truly
essential class, for which the set of (upper or lower)
local dimensions is a closed interval. Within the truly
essential class we show that there exists a point with
local dimension exactly equal to the dimension of the
support. We give an example where the set of local
dimensions is a two element set, with all the elements
of the truly essential class giving the same local
dimension. We give general criteria for these measures
to be absolutely continuous with respect to the
associated Hausdorff measure of their support and we
show that the dimension of the support can be computed
using only information about the essential class. To
conclude, we present a detailed study of three
examples. First, we show that the set of local
dimensions of the biased Bernoulli convolution with
contraction ratio the inverse of a simple Pisot number
always admits an isolated point. We give a precise
description of the essential class of a generalized
Cantor set of finite type, and show that the $ k t h $
convolution of the associated Cantor measure has local
dimension at $ x \in (0, 1) $ tending to 1 as $k$ tends
to infinity. Lastly, we show that within a maximal loop
class that is not truly essential, the set of upper
local dimensions need not be an interval. This is in
contrast to the case for finite type measures with
regular probabilities and full interval support.",

In some particular cases, namely if $L$ is a boundary

however no formula is known in general. In this

into the range of an associated analytic Toeplitz
operator and an identifiable orthogonal complement. For
certain cases, we compute this orthogonal complement in

spirit of Ahern-Clark, we also discuss the
non-tangential boundary behavior in these range spaces.
These results give us further insight into the
description of the range of a co-analytic Toeplitz

Ahern-Clark type results, which are stated in a general
