Résume | I will discuss recent results establishing hyperfiniteness of
equivalence relations induced by actions on Gromov boundaries of various
hyperbolic spaces. This includes boundary actions of hyperbolic groups
(joint work with T. Marquis) and actions of the mapping class group on
boundaries of the arc graph and the curve graph (joint work with P.
Przytycki) |
