Benjamin Barrett, Zoom: Hyperbolic groups with locally simply connected boundaries
Thursday, April 08, 2021, 12:30pm - 01:30pm
A hyperbolic group admits a compactification at infinity, called its Gromov boundary. These spaces can be quite complicated, and I will begin giving some examples to illustrate this. I will then describe a result that restricts the topological pathologies of a Gromov boundary by characterising the circumstances under which the boundary is locally simply connected. This can be thought of as a higher dimensional analogue of a theorem of Bestvina and Mess.
