Title: Entropy methods in Markov chains

Abstract: Building upon Yau's relative entropy method, we derive a new strategy to obtain scaling properties of Markov chains with a large number of components. As an application, we obtain very precise estimates on the mixing properties of a mean-field spin system. Time permitting, we will also discuss the derivation of the speed of convergence of the hydrodynamic limit and non-equilibrium fluctuations of interacting particle systems.

October 17: Christian Webb (Aalto)

Title: On the statistical behavior of the Riemann zeta function

Abstract: A notoriously difficult problem of analytic number theory is to describe the behavior of the Riemann zeta function on the critical line. After reviewing some basic facts about the zeta function, I will discuss what can be said if the problem is relaxed by considering the behavior of the zeta function in the vicinity of a random point on the critical line.

Time permitting, I will also discuss how this problem is related to various models
of probability theory and mathematical physics. The talk is based on joint work with Eero Saksman.
