On random walks on the mapping class group

Geometric Topology 2025-07-15 v1

Abstract

We define an electrification of the curve graph of a surface S of finite type and use it to identify the Poisson boundary of a random walk on the mapping class group of S with some logarithmic moment condition as a stationary measure on the space of minimal and maximal geodesic laminations on SS, equipped with the Hausdorff topology.
