Finiteness of arithmetic hyperbolic reflection groups

We prove that there are only finitely many maximal arithmetic hyperbolic reflection groups in all dimensions. The talk will define the objects discussed in this theorem, and outline the proof. This has been proven independently by Nikulin, using different techniques. This is joint work with Mikhail Belolipetsky, Peter Storm, and Kevin Whyte.
