Colloquium: Tuesday, November 27, 2018. Speaker: Nir Lazarovich (Technion). Title: “Surface-like boundaries of hyperbolic groups”.
Place: Room 614 in the Education & Sciences Building
Date: Tuesday, November 27, 2018
Hyperbolic groups were introduced by Gromov to create a unified framework for various notions of non-positive curvature in group theory. To a hyperbolic group one can assign a boundary at infinity on which the group acts. The topological spaces that appear as boundaries of hyperbolic groups are beautiful fractals that merit studying on their own right. In this talk I will discuss hyperbolic groups and their boundaries in general, and a joint work with Benjamin Beeker on surface-like boundaries of hyperbolic groups.
Tea will be served before the talk (at 13:50).
