DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSUGGT/15/">
 Hyperfiniteness at Gromov boundaries</a>\nby Marcin Sabok (McGill Universi
 ty) as part of Ohio State Topology and Geometric Group Theory Seminar\n\n\
 nAbstract\nI will discuss recent results establishing hyperfiniteness of e
 quivalence relations induced by actions on Gromov boundaries of various hy
 perbolic spaces. This includes boundary actions of hyperbolic groups (join
 t work with T. Marquis) and actions of the mapping class group on boundari
 es of the arc graph and the curve graph (joint work with P. Przytycki)\n
