Description
Given a hyperbolic 3-manifold M, we will define a topology on AH(M), the space of (marked) hyperbolic
3-manifolds homotopy equivalent to M. This space has connections with the Teichmuller space of a surface,
quasiconformal maps on the sphere, and hyperbolic geometry. We will define all of these objects, discuss two
equivalent definitions of AH(M), and characterize the interior of AH(M) as the set of convex cocompact hyperbolic
3-manifolds. Following the necessary background, we will outline a proof that (given some mild assumptions on M)
the interior of AH(M) is homeomorphic to a product of Teichmuller spaces.
