Title: Boundaries of Kleinian groups
Speaker: Genevieve Walsh (Tufts University)
Seminar URL: https://research.math.osu.edu/topology/#6433560
Abstract: We consider hyperbolic groups with boundaries homeomorphic to the boundaries of certain types of Kleinian groups. We show that a hyperbolic group quasi-isometric to a mixed Kleinian surface group is virtually a mixed Kleinian surface group. Furthermore, in this case, the rigid pieces of the two groups are commensurable. This is joint work with Peter Haissinsky and Luisa Paoluzzi.
