On groups with $S^2$ Bowditch boundary

Group Theory 2021-10-12 v3

Abstract

We prove that a relatively hyperbolic pair (G,P)(G,P) has Bowditch boundary a 2-sphere if and only if it is a 3-dimensional Poincare duality pair. We prove this by studying the relationship between the Bowditch and Dahmani boundaries of relatively hyperbolic groups.
