Annular and boundary reducing Dehn fillings
Cameron McA. Gordon, Ying-Qing Wu
A manifold M is simple if it contains no essential disk, sphere, annulus or torus. If M is simple and two Dehn fillings M(r_1), M(r_2) are nonsimple, then there is an upper bound o…

Toroidal and Boundary-Reducing Dehn Fillings
C. McA. Gordon, J. Luecke
Let M be a simple 3-manifold with a toral boundary component partial_0 M. If Dehn filling M along partial_0 M one way produces a toroidal manifold and Dehn filling M along partial_…
