Our first result is an extension of the sum-product theorem from [8] when sets of different sizes are involved. It is shown that if and p$^{\varepsilon }$ < |B|, |C| < |A| < p$^{1 - \varepsilon }$, then |A + B| + |A \cdotp C| > p$^{\delta (\varepsilon)}$ |A|. Next we exploit the Szemer{\'e}di--Trotter theorem in finite fields (also obtained in [8]) to derive several new facts on expanders and extractors. It is shown for instance that the function f(x,y) = x(x+y) from to satisfies |F(A,B)| > p$^{\beta }$ for some \beta = \beta (\alpha) > \alpha whenever and $ |A| \sim |B| \sim p^\alpha $, $ 0 < \alpha < 1$. The exponential sum $ \sum_{x \in A, y \in B}$ \varepsilon$_p$ (axy+bx$^2$ y$^2$), ab \neq 0 (mod p), may be estimated nontrivially for arbitrary sets satisfying |A|, |B| > p$^{\rho }$ where \rho < 1/2 is some constant. From this, one obtains an explicit 2-source extractor (with exponential uniform distribution) if both sources have entropy ratio at last \rho. No such examples when \rho < 1/2 seemed known. These questions were largely motivated by recent works on pseudo-randomness such as [2] and [3]. Finally it is shown that if p$^{\varepsilon }$ < |A| < p$^{1 - \varepsilon }$, then always |A + A|+|A$^{-1}$ + A$^{-1}$ | > p$^{\delta (\varepsilon)}$ |A|. This is the finite fields version of a problem considered in [11]. If A is an interval, there is a relation to estimates on incomplete Kloosterman sums. In the Appendix, we obtain an apparently new bound on bilinear Kloosterman sums over relatively short intervals (without the restrictions of Karatsuba's result [14]) which is of relevance to problems involving the divisor function (see [1]) and the distribution (mod p) of certain rational functions on the primes (cf.

The representation \pi_Y is normalizedly induced from, m_i \in GL(i, F), on the maximal parabolic subgroup of type (3, 1); \theta is the ``transpose-inverse'' involution of G. We show that the twisted character \chi_{\pi Y} of \pi_Y is an unstable function: its value at a twisted regular elliptic conjugacy class with norm in C_Y = C_Y (F)=``(GL(2, Y)/F^{\times})_F is minus its value at the other class within the twisted stable conjugacy class. It is 0 at the classes without norm in C_Y. Moreover \pi_Y is the endoscopic lift of the trivial representation of C_Y. We deal only with unramified Y/F, as globally this case occurs almost everywhere. The case of ramified Y/F would require another paper. Our C_Y = ``(R_{Y/F} GL(2)/GL(1))_F '' has Y-points C_Y (Y) = {(g, g\prime) \in GL(2, Y) \times GL(2, Y); det(g) = det(g\prime)}/Y^{\times} (Y^{\times} embeds diagonally); \sigma(\neq 1) in Gal(Y/F) acts by \sigma (g, g\prime) = (\sigma g\prime, \sigma g). It is a \theta -twisted elliptic endoscopic group of GL(4). Naturally this computation plays a role in the theory of lifting of C_Y and GSp(2) to GL(4) using the trace formula, to be discussed elsewhere. Our work extends --- to the context of nontrivial central characters --- the work of [7], where representations of PGL(4, F) are studied. In [7] we develop a 4-dimensional analogue of the model of the small representation of PGL(3, F) introduced by the first author and Kazhdan in [5] in a 3-dimensional case, and we extend the local method of computation introduced in [6].

The complication that arises for G = SL(3,R) comes from the fact that there are now two fundamental representations. This has the consequence that the wave operator, which plays a central role in our work on SL(2,R) is replaced by an overdetermined system of partial differential equations. The analog of the wave operator is defined using an MN invariant orbit of G acting on the direct sum of the symmetric squares of the fundamental representations. The relation of orbits, or, in general, of any algebraic variety, to a system of partial differential equations comes via the Fundamental Principle, which shows how Fourier transforms of functions or measures on an algebraic variety correspond to solutions of the system of partial differential equations defined by the equations of the variety. In particular, we can start with the sum T of the delta functions of the orbit of the group \Gamma = SL(2,Z) on the light cone. We then take its Fourier transform, using a suitable quadratic form. We then decompose the Fourier transform under the commuting group of G. In this way, we obtain a \Gamma invariant distribution which has a natural restriction to the orbit G/K, which is the symmetric space of G. This restriction is (essentially) the nonanalytic Eisenstein series. We can compute the periods of the Eisenstein series over various orbits of subgroups of G by means of the Euclidean Plancherel formula.
