SUMMARY:TQFTs\, Skein Modules and Knots in 3-Manifolds - Oliver Singh (Dur

DESCRIPTION:The Jones polynomial can be defined in several ways including 
 as an\nevaluation of a Topological Quantum Field Theory (or TQFT) and usin
 g the\nKauffman skein relation. Either generalises to give an invariant fo
 r\nknots in a three manifold. The latter generalisation has a simple\ndesc
 ription as an element of a 'skein module'. I will introduce all of\nthese 
 concepts and\, motivated by this example\, tell you about TQFTs and\nskein
  modules. I will also talk about categorification of these objects\nand ta
 lk about applications to 3 and 4 dimensional topology.
