   Speaker: Stefan Witzel (Bielefeld University)

   Title:  Arithmetic groups, finiteness properties, and homology

   Abstract: The group SL_2(F_p[t,t^{-1}]) is finitely generated but not
finitely presented. In fact, it has a finite-index subgroup G with
H_2(G,F_p) infinite (this and more was shown by Stuhler). I will talk about
results of the same kind for related groups.
