ABSTRACT  |  The cosmetic surgery conjecture says that there is no pair of Dehn surgeries on a non-trivial knot that yield homeomorphic 3-manifolds preserving orientation. We will introduce some recent progress on this conjecture and discuss several 3-manifold invariants that are relevant to this problem. Part of this talk is based on joint work with Yi Ni and joint work with Kazuhiro Ichihara.
