Abstract or Additional Information
I will introduce the Dehn surgery construction in the study of 3-manifolds, relate it to the mapping class group of the torus (i.e. genus-one surface), and interpret these in the appropriate bordism category. Then I will introduce TQFT and survey some things it has to say about this construction.
