Toroidal Dehn fillings on large hyperbolic 3-manifolds

Geometric Topology 2007-05-23 v1

Abstract

We show that if a hyperbolic 3-manifold MM with a single torus boundary admits two Dehn fillings at distance 5, each of which contains an essential torus, then MM is a rational homology solid torus, which is not large in the sense of Wu. Moreover, one of the surgered manifold contains an essential torus which meets the core of the attached solid torus minimally in at most two points. This completes the determination of best possible upper bounds for the distance between two exceptional Dehn fillings yielding essential small surfaces in all ten cases for large hyperbolic 3-manifolds.
