Dani Wise will give a series of talks April 19-21 (before the workshop) on his work on separability for hyperbolic groups with quasiconvex hierarchies. The workshop proper will run for two days (April 22-23) and will focus on topics related to the virtual positive first Betti number conjecture and virtual fibering conjectures for 3-manifolds. Michel Boileau will be giving the Montreal-area mathematics colloquium on Friday April 23 to close the event.
