Reducing Dehn fillings and small surfaces
Sangyop Lee, Seungsang Oh, Masakazu Teragaito
In this paper we investigate the distances between Dehn fillings on a hyperbolic 3-manifold that yield 3-manifolds containing essential small surfaces including non-orientable surf…

P^2-reducing and toroidal Dehn fillings
Gyo Taek Jin, Sangyop Lee, Seungsang Oh +1
We study the situation where we have two exceptional Dehn fillings on a given hyperbolic 3-manifold. We consider two cases that one filling creates a projective plane, and the othe…

Dehn fillings creating essential spheres and tori
Sangyop Lee, Seungsang Oh, Masakazu Teragaito
Let be a simple 3-manifold with a toral boundary component. It is known that if two Dehn fillings on along the boundary produce a reducible manifold and a toroidal manifold…
