Ping-pong dynamics of hyperbolic-like actions with non-simple points

Abstract

A hyperbolic-like group is a subgroup of ${\mathrm{Homeo}}_{+}(S^1)$ such that every non-trivial element has exactly two fixed points, one attracting and one repelling. We investigate the ping-pong dynamics of hyperbolic-like groups, inspired by a conjecture of Bonatti. We show the existence of a proper ping-pong partition for any pair of non-cyclic point stabilizers. More precisely, our results explicitly provide such a ping-pong partition.
