"Algorithms for the topology of arithmetic groups"
Integer matrix Lie groups \Gamma carry extremely deep arithmetic information. Topological invariants of \Gamma are particularly interesting. I will describe an algorithm which, given \Gamma, computes the homology of \Gamma together with the action of certain correspondences on it (Hecke operators). Joint work with Aurel Page.
