Mathematik und Informatik

Abstract: Let G be an arithmetic group like SL(n,Z). Borel and Serre proved a beautiful theorem showing that the topology of G ?at infinity? can be modeled by an appropriate Tits building. I will discuss a circle of ideas combining insights from topology, number theory, and representation theory to use this to shed light on G and its subgroups.
