Title: The Floyd boundary of a hyperbolic group is its Gromov boundary.
Speaker: Christopher Cashen
Abstract: Using the Gehring-Hayman theorem on conformal deformations of the plane and its generalization to Gromov hyperbolic spaces, we will show that the Floyd boundary of a hyperbolic groups is the same as its Gromov boundary. If there is time, I'll also talk a little about relatively hyperbolic groups and their boundaries.
