Groups, Dynamics and Related Topics - Guy Salomon (Technion)
28/05/2015, Thursday, 14:45
Type : Seminar
Name : Groups, Dynamics and Related Topics
Title : The Furstenburg boundary of a discrete group via operator space methods and applications (following Kalantar and Kennedy), II
Speaker : Guy Salomon (Technion)
Place : Amado 814, Technion
In this second talk we will survey applications of last weeks construction to the problems of C*-simplicity and nuclear embedability of the reduced C*-algebra of a discrete group. Time permitting, some further application to C*-simplicity due to Breuillard, Kalantar, Kennedy and Ozawa will also be discussed.

Geometry and Topology Seminar - Kate Juschenko (Northwestern)

Type : Seminar
Name : Geometry and Topology Seminar
Title : On subgroups of interval exchange transformation group
Speaker : Kate Juschenko (Northwestern)
Place : Amado 814, Technion
I will give a survey talk on the group of interval exchange transformations, and properties of its subgroups. The group does not have property (T) subgroups, it can serve as a good source of simple finitely generated infinite groups. I will also discuss several approaches to the main open question on this group: the existence of free non-abelian subgroups.

Colloquium - Catherine Bandle (Basel)

Title : Stability results for solutions of semi linear elliptic equations on Riemannian manifolds
Speaker : Catherine Bandle (Basel)
Place : Sego 1, Technion

We study the stability and instability of equilibrium solutions of a reaction-diffusion equationwith different types of boundary conditions. Stable solutions play an important role in thestudy of pattern formation in biology. Unstable solutions lack of physical significance. it turnsout that the stability depends on the curvature of the manifold and the geometric propertiesof the boundary. The main tool is the Bochner-Weitzenböck formula. The talk is intended to givea flavor of how to apply this formula and does not require any knowledge of geometric analysis.

Title : Borell's formula for a Riemannian manifold
Speaker : Joseph Lehec
Place : Meyer bldg (elec. eng.), room 861. Technion, Haifa., Technion
Borell's formula is a stochastic variational formula for the log-Laplace transform of a function of a Gaussian vector. We shall present an extension of this to the Riemannian setting. As an application we will give a new proof of the Brascamp-Lieb inequality on the sphere (due to Carlen, Lieb and Loss).

Title : Markov chains with asymptotically zero drift: asymptotic behavior of passage times
Speaker : Vitali Wachtel (Augsburg)
Place : Meyer bldg (elec. eng.), room 861. Technion, Haifa., Technion
Let X_n be a Markov chain on R_+ with the following asymptotics of first and second moments:
E [X_1-X_0|X_0=x] ~ -\mu/x, as x \to \infty,
E [(X_1-X_0)^2|X_0=x] ~ b \in (0,\infty), as x \to \infty.

In this talk I shall describe the tail behavior of the stopping time
\tau_A:=\min\{n \geq1: X_n \leq A\} in the recurrent case \mu>-b/2.
Furthermore, I shall discuss the asymptotic behavior of X_n conditioned on \tau_A>n.

An e-mail will be sent in the next few days to thoses registered. If you have registered and did not recieve an e-mail by April 12, please contact cms@math.technion.ac.il

Important Note: When booking your flight, please take into consideration that the conference shuttle leaves on June 17th at 11:30am from Binyamina railway station, which is one hour by train from Ben Gurion airport. We thus recommend that you arrive either in the early morning of the 17th, or at the 16th. In the latter case we can help you find accommodation in Tel Aviv or Haifa for the night.

The  following mini-courses will be given:

Michel Brion (Institute Fourier) "Spherical Varieties"

Kai-Uwe Bux (Universität Bielefeld) "Finiteness Properties of Arithmetic Groups"

Dima Gourevitch (Weizmann Institute) "Multiplicity One Spaces"

Place : Amadi 814, Technion

ISF- The Israeli Science Foundation     CMS- Center for Mathematical Science

Coloring Graphs at the Technion

Graph Coloring and Chi –boundedness with Algebra, Topology and Probability

The goal of this informal workshop is to bring together researchers in an attempt of a focused attack on some long standing problems in graph coloring. The workshop will deal with variants on classical graph coloring, and related problems, such as cooperative colorings, χ-boundedness, Reed's conjecture and strong colorings.

We have gathered a group of experts in a broad spectrum of areas of Discrete Mathematics, and we hope to benefit from their diverse branches of expertise. Thus, we expect to use approaches such as topological methods, structural tools and the probabilistic method.
