Zlil Sela and Alex Lubotzky "Model theory of groups"
In the first part of the course we will present some of the main results in the theory of free,
hyperbolic and related groups, many of which appear as lattices in rank one simple Lie groups
We will present some of the main objects that are used in studying the theory of these groups,
and at least sketch the proofs of some of the main theorems.
In the second part of the course, we will talk about the model theory of lattices in high rank simple Lie groups.
The latter behave very differently from the first. These lattices are all arithmetic ( by Margulis seminal work)
and their model theory is related to other properties, like super-rigidity, bounded generations, the congruence
subgroup problem and more.
All needed material will be explained. Sun, 10 Mar 2019 09:00:00 +0000Anonymous79155 at https://mathematics.huji.ac.il<a href="https://mathematics.huji.ac.il/event/special-logic-seminar-tomer-schlank?delta=0" >Special logic seminar - Tomer Schlank</a>

https://mathematics.huji.ac.il/event/ari-shnidman-geometric-expressions-derivatives-l-functions-automorphic-forms-after-yun
Yun and Zhang compute the Taylor series expansion of an automorphic L-function over a function field, in terms of intersection pairings of certain algebraic cycles on the so-called moduli stack of shtukas. This generalizes the Waldspurger and Gross-Zagier formulas, which concern the first two coefficients.
The goal of the seminar is to develop the background necessary to state their formula, and then indicate the structure of the proof. If time allows, we may also discuss applications to the Birch and Swinnerton-Dyer conjecture for elliptic curves over function fields.
Tentative plan:
(a) Automorphic forms over function fields and their L-functions.
(b) Waldspurger's formula
(c) Relative trace formula
(d) Intersection theory on smooth algebraic varieties (and smooth stacks)
(e) Moduli spaces of Drinfeld's stukas
(f) Formula of Yun and Zhang
(g) Outline of proof

Title: Mesoscopic universality for orthogonal polynomial ensembles on the unit circle
Abstract: Orthogonal polynomial ensembles (OPE) on the unit circle are a certain class of point processes that arise naturally in random matrix theory and statistical mechanics. One special case of such a process is the extensively studied Circular Unitary Ensemble. In this talk we discuss the connection between OPE's and orthogonal polynomials on the unit circle. In particular, we show that in order to study asymptotics of the mesoscopic fluctuations of the empirical measure it is sufficient to understand the asymptotics of the associated recurrence coefficients. This is joint work with J. Breuer.

https://mathematics.huji.ac.il/event/colloquium-0
<u>Abstract:</u> <br /><br />In Gromov-Witten theory, one studies various invariants which<br />are constructed using the moduli space of pseudo-holomorphic curves in a<br />symplectic manifold M . A concrete example is the number of rational cubics<br />which pass through 8 points in general position in P 2 . Such invariants can<br />be defined and computed by integrating certain cohomology classes over the<br />moduli space of curves. More refined invariants can be defined using Chern<br />classes of certain tautological lines bundles which live on the moduli space.<br />Those invariants are called descendant invariants.<br /><br />In open Gromov-Witten theory, the invariants come from the moduli<br />space of stable pseudo-holomorphic disks in M with boundary inside a La-<br />grangian submanifold L. We will present an approach to defining open<br />descendant invariants using the framework of A ∞ -algebras and bounding<br />chains. By constructing connections on the tautological line bundles that<br />satisfy recursive compatibility conditions we deform the algebra of differ-<br />ential forms on L into an A ∞ algebra which incorporates the gravitational<br />descendants. One then uses the notion of a bounding chain to define the<br />invariants and obtain a generating function.<br /><br />This is joint work with Jake Solomon. An honest attempt will be made to<br />make the presentation as elementary and accessible as possible for general<br />audienceThu, 20 Jun 2019 11:30:00 +0000Anonymous63604 at https://mathematics.huji.ac.il<a href="https://mathematics.huji.ac.il/event/basic-notions-hillel-furstenberg-huji-affine-convex-representations-and-harmonic?delta=0" >Basic Notions: Hillel Furstenberg (HUJI) : "Affine (Convex) representations and harmonic functions on symmetric spaces."</a>
https://mathematics.huji.ac.il/event/basic-notions-hillel-furstenberg-huji-affine-convex-representations-and-harmonic
Classical group representation theory deals with group actions on linear spaces; we consider group actions on compact convex spaces, preserving topological and convex structure. We focus on irreducible actions, and show that for a large class of groups - including connected Lie groups - these can be determined. There is a close connection between this and the theory of bounded harmonic functions on symmetric spaces and their boundary values. A remarkable phenomenon is the fact that for SL(2,R), up to isomorphism, there exists a unique non-degenerate irreducible affine representation.Thu, 20 Jun 2019 13:00:00 +0000Anonymous85981 at https://mathematics.huji.ac.il<a href="https://mathematics.huji.ac.il/event/zlil-sela-and-alex-lubotzky-model-theory-groups?delta=14" >Zlil Sela and Alex Lubotzky "Model theory of groups"</a>

<strong>Gili Golan:</strong> <strong>Divergence functions of Thompson groups</strong>.<br />The divergence function of a group generated by a finite set X is the smallest function f(n) such that for every n any pair of elements of length n can be connected in the Cayley graph (corresponding to X) by a path of length at most f(n) avoiding the ball of radius n=4 around the identity element. We prove that R. Thompson groups F, T, and V have linear divergence functions. Therefore the asymptotic cones of these groups do not have cut points. This is joint work with Mark Sapir.
</p>
<p style="text-align:justify">
<strong>Marcel Herzog: On the orders of elements in nite and periodic groups.</strong><br />Part A of the talk will deal with problems related to the spectrum of periodic groups, which denotes the set of element orders in such groups. <br />Part B of the talk will deal with problems related to the multisets of all element orders in finite groups, in particular the sums of these orders.
</p>
<p style="text-align:justify">
<strong>Chen Meiri: First order rigidity of higher-rank arithmetic groups.</strong><br />In many contexts, there is a dichotomy between lattices in Lie groups of rank one and lattices in Lie groups of higher-rank. I will talk about a manifestation of this dichotomy in Model Theory.<br />Based on joint works with Nir Avni and Alex Lubotzky.
</p>
<p style="text-align:justify">
<strong>Shifra Reif: Denominator identities for periplectic Lie superalgebras.</strong><br />Identities involving symmetric functions often have a deep meaning in representation theory, as in case of the Amitsur–Levitzky identity and Macdonald’s identities.<br />The latter are in fact denominator identities for affine Lie algebras, that is they are obtained by applying the Kac–Weyl character formula for the trivial representation.<br />In this talk I will present polynomial identities which are denominator identities of the periplectic Lie superalgebra p(n). We shall discuss their origin and homological meaning.

<strong>Zlil Sela: Basic conjectures and preliminary results in non-commutative algebraic geometry.</strong><br />Algebraic geometry studies the structure of sets of solutions (varieties) over fields and commutative rings. Starting in the early 1960’s ring theorists (Cohn, Bergman, Amitsur and others) have tried to study the structure of varieties over non-commutative rings (notably free associative algebras). The lack of unique factorization that they tackled and studied in detail, and the pathologies that they were aware of, prevented any attempt to prove or even speculate what can be the properties of such varieties.<br />Using techniques and concepts from geometric group theory and from low dimensional topology, we formulate concrete conjectures on the structure of these varieties, and prove preliminary results in the direction of these conjectures.

"Geometrization of the local Langlands program"
Abstract: The Langlands program links automorphic forms and Galois representations (of a local or global field). In contrast, the geometric Langlands program takes a curve X over the complex numbers, and links the moduli space of rank n vector bundles on X to rank n local systems on X. A beautiful program initiated by Fargues reveals the unity of the two programs over the field of p-adic numbers. In this program, the role of X is played by the Fargues-Fontaine curve. The goal of this series of lectures is to understand Fargues' suite of conjectures. The conjectures are a theorem in the case of n = 1, where one recovers local class field theory in a new way.

https://mathematics.huji.ac.il/event/group-and-dynamics-seminar-asaf-naor-princeton
Abstract: A Markov chain over a finite state space is said to exhibit the total variation cutoff phenomenon if, starting from some Dirac measure, the total variation distance to the stationary distribution drops abruptly from near maximal to near zero. It is conjectured that simple random walks on the family of $k$-regular, transitive graphs with a two sided $\epsilon$ spectral gap exhibit total variation cutoff (for any fixed $k$ and $\epsilon). This is known to be true only in a small number of cases. In this talk we discuss a new family of such graphs that exhibit cutoff, namely the $1$-skeleton of Ramanujan complexes. This family is the first natural one -- occurring as Cayley graphs of $PGL(d, q)$ -- for which the cutoff point is at a non-optimal time. Joint work with Ori Parzanchevski.Thu, 27 Jun 2019 07:00:00 +0000Anonymous82733 at https://mathematics.huji.ac.il<a href="https://mathematics.huji.ac.il/event/colloquium?delta=0" >Colloquium Dvoretzky lecture: Assaf Naor(Princeton) - An average John theorem </a>
