Type : Seminar
Name : Seminar in Probability and Stochastic Processes
Title : Coupling Toom Interfaces
Speaker : Nick Crawford (Technion)
Place : 861 Meyer Building (Hashmal), Technion
Abstract    
In this talk, I will introduce an interesting one dimensional interacting particle system related to a famous probabilistic cellular automata called Toom’s model.
The state space of this particle system may be taken to be either {-1, 1}^Z or {-1, 1}^N and the dynamics is defined such that there is a single parameter, call it p, controlling the relative rate at which the ±1’s change there states (p=1/2 being the unbiased case).  The particle system has a number of remarkable features.  First and foremost, when defined on N, it has a unique invariant measure for each choice of p.  Moreover, if one asks about the scaling of the variance of the first L spins with L, it has been conjectured to scale as L^{2/3} if p is not 1/2 and L^{1/2} up to logarithmic corrections if p=1/2 (recall that for independent spins, the scaling is L).  These exponents are thought to directly reflect the fact that the dynamical behavior of fluctuations is governed by either the Kardar-Parisi-Zhang equation (if p is not 1/2) or by the stochastic heat equation with a few caveats (if p=1/2).
In this talk I will describe recent work joint with G. Kozma and W. de Roeck motivated by the picture described above.

PDE and Applied Mathematics Seminar - Gershon Wolansky (Technion)

Type : Seminar
Name : PDE and Applied Mathematics Seminar
Title : Optimal partitions: Individual values, monopoles and partition games
Speaker : Gershon Wolansky (Technion)
Place : Amado 814, Technion
Abstract    

I'll consider an optimal partition of  resources (e.g. customers) between several agents (e.g. experts), given utility functions for the agents and their capacities. This problem is a  variant of  optimal transport (Monge-Kantorovich) between two measure spaces   where one of the measures  is discrete (capacities) and the cost of transport is the  utilities  of agents. I'll concentrate on the individual  value  for each agent under optimal partition  and show that, counter-intuitively, this value may decrease if the agent's utility is increased.   Sufficient  and necessary conditions    for increment of the individual value  will be given, independently of the other agents. The sharpness of these conditions will be discussed, as well.If time permit I'll discuss some applications to cooperative games.

Combinatorics Seminar - Ehud Friedgut (Weizmann)
27/05/2015, Wednesday, 13:30
Type : Seminar
Name : Combinatorics Seminar
Title : An information theoretic proof of a hypercontractive inequality
Speaker : Ehud Friedgut (Weizmann)
Place : Amado 619, Technion
Abstract    

In the famous KKL (Kahn-Kalai-Linial) paper of 1988 the authors "imported" to combinatorics and theoretical computer science a hypercontractive inequality known as Beckner's ineqaulity (proven first, independently, by Gross and Bonami). This inequality has since become an extremely useful and influential tool, used in tens of papers, in a wide variety of settings. In many cases there are no proofs known that do not use the inequality.

In this talk I'll try to illuminate the information theoretic nature of both the inequality and its dual, touch upon a proof of the dual version from about a decade ago, (joint with V. Rodl), and a fresh (and unrelated) information theoretic proof of the primal version.

No prior knowledge will be assumed regarding discrete Fourier analysis, Entropy, and hypercontractivity.

Colloquium - Catherine Bandle (Basel)

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

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.

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.
