Title: An Effective Compactness Theorem for Coxeter groups

Abstract:

Spaces of hyperbolic structures can be extremely pathological, and

compactness theorems for these spaces tend to be highly non-

constructive.

After a introduction to Coxeter groups and hyperbolic structures, I will

discuss recent results and an effective compactness theorem for the

space of hyperbolic structures of Coxeter groups.
