Title: Expansion in hyperbolic groups

Abstract:  In this talk I'll discuss recent results about growths of product sets in hyperbolic groups: If G is a hyperbolic group and A, B are two finite sets, how large can |AB| be? I'll also talk about applications of such theorems to the theory of approximate groups. Based on a joint work with Michael Saks, https://arxiv.org/abs/2606.13632 .
