Title

:

"Mean ergodic theorems : from amenable to non-amenable groups"
Abstract

:

We will trace the evolution of the mean ergodic theorem, from its original formulation by von-Neumann to some very recent formulations valid in the context of algebraic groups and their lattice subgroups. We will then present a variety of recent applications of mean ergodic theorems, particularly to counting lattice points. Based partly on joint work with Alex Gorodnik.
