Linear Progress with Exponential Decay in Weakly Hyperbolic Groups

Geometric Topology 2021-01-22 v1

Abstract

A random walk wnw_n on a separable, geodesic hyperbolic metric space XX converges to the boundary X\partial X with probability one when the step distribution supports two independent loxodromics. In particular, the random walk makes positive linear progress. Progress is known to be linear with exponential decay when (1) the step distribution has exponential tail and (2) the action on XX is acylindrical. We extend exponential decay to the non-acylindrical case.
