Hello everyone,

Tomorrow we will be holding usual seminar. I will be speaking. My title and abstract are below.


Title: Exceptional Surgeries in 3-manifolds

Abstract: Bob (Myers) shows that every compact, connected, orientable 3–manifold with no 2– sphere boundary components contains a hyperbolic knot. We use work of Ikeda with an observation of Adams-Reid to show that every 3–manifold subject to the above conditions contains a hyperbolic knot which admits a non-trivial non-hyperbolic surgery, a toroidal surgery in particular. We conclude with a question and a conjecture about reducible surgeries. This is joint work with Ken Baker.
