Title |
Large-scale geometry of lattices in semisimple groups |
Abstract |
I’ll talk about comparisons that can be made in geometric group theory between classical arithmetic groups such as SL(n,Z) and arithmetic groups over function fields such as SL(n,F[t]) where F is a finite field. I’ll also try to explain how sometimes these classes of groups exhibit their similar tendencies through contrasting behavior. Topics to be covered include quasi-isometric rigidity, finiteness properties, and if time permits, Dehn functions of groups. |
