Contact 3-manifolds are smooth 3-manifolds which carry a special geometric structure. A way to get new contact manifold is via contact surgery. One could think of this procedure as an analogue of Dehn surgery in the smooth world.
In this talk, I'll briefly define contact surgery and its applications. I'll also mention some of the open problems which I find interesting. Next I'll talk about contact surgery numbers. Part of this will be joint work with Marc Kegel.
