Growth tightness of quotients by confined subgroups

Group Theory 2024-09-17 v1 Geometric Topology

Abstract

In this paper, we establish the growth tightness of the quotient by confined subgroups in groups admitting the statistically convex-cocompact action with contracting elements. The result is sharp in the sense that the actions could not be relaxed with purely exponential growth. Applications to uniformly recurrent subgroups are discussed.
