Abstract:
We will present a new proof of the Brock-Canary-Minsky ending lamination theorem. As in the original proof, our starting point will be Minsky’s a priori bounds on the length of certain closed geodesics in hyperbolic 3-manifolds homotopy equivalent to a surface. From there the two proof’s diverge. Roughly speaking we avoid many of the difficult geometric limit arguments of the original proof by using the techniques of grafting and drilling. This is joint work with J. Brock, R. Evans and J. Souto.
