Boundary rigidity for hyperbolic groups

By Kathryn Mann

Also appears in collection : 2022 - T2 - WS3 - Hyperbolic groups and their generalisations

I will motivate and explain recent joint work with Jason Manning and Teddy Weisman that shows that the action of a hyperbolic group on its boundary is stable in the sense of topological dynamics, meaning that any sufficiently small perturbation of the action is semi-conjugate to the original action.
