The Jones polynomial can be defined in several ways including as an evaluation of a Topological Quantum Field Theory (or TQFT ) and using the Kauffman skein relation. Either generalises to give an invariant for knots in a three manifold. The latter generalisation has a simple description as an element of a ‘skein module’. I will introduce all of these concepts and, motivated by this example, tell you about TQF Ts and skein modules. I will also talk about categorification of these objects and talk about applications to 3 and 4 dimensional topology.
