Nir Lazarovich: Average distortion of commensurators of hyperbolic groups

Organisé par

Institut Henri Poincaré

Abstract: We will discuss isomorphisms between finite index subgroups of hyperbolic groups and their average distortion (to be defined in the talk). I will present the main ingredients in proving that the average distortion of a residually finite rigid hyperbolic group is bounded, and discuss some corollaries. While this talk can be seen as a continuation of the talk I gave in the GGD seminar, in
