Title:  The virtual Haken conjecture

Abstract:   In the third talk, I'll discuss the proof that cubulated hyperbolic

groups are virtually special. The proof relies on results of Haglund

and Wise which also imply that they are linear groups, and

quasi-convex subgroups are separable. A consequence is that closed

hyperbolic 3-manifolds have finite-sheeted Haken covers, which

resolves the virtual Haken question of Waldhausen and Thurston�s

virtual fibering question. Crucial contributions come from

Kahn, Markovic, Wise and collaborators in resolving these conjectures.
