| Research Abstract |
I introduced the notion of ruled wrappings and by using it gave a simple alternative proof of Marden's conjecture. We completed the geometric classification of geometric limits hyperbolic manifolds which are given by geometric limits of sequences of hyperbolic 3-manifolds with fundamental groups isometric to compact surface groups. In particular, we proved that, if these two geometric manifolds are homeomorphic and have the same end invariants, the homeomorphism is properly homotopic to an isometry.
