I will define character varieties of finitely generated groups and consider some applications of them in geometry/topology.

I will give an example of transforming a knot into closed braid form
using Yamada-Vogel algorithm. From this we can write down the
corresponding element of the knot in the braid group. Finally, the
definition of a colored Jones polynomial is given using a Yang-Baxter
operator. This is a preparation for next week's talk by Anh.

( This will be a continuation of last week's talk. )An n-dimensional topological quantum field theory is a functor from the
category of closed, oriented (n-1)-manifolds and n-dimensional cobordisms to
the category of vector spaces and linear maps. Three and four dimensional
TQFTs can be difficult to describe, but provide interesting invariants of
n-manifolds and are the subjects of ongoing research.
This talk focuses on the simpler case n=2, where TQFTs turn out to be
equivalent, as categories, to Frobenius algebras. I'll introduce the two
structures -- one topological, one algebraic -- explicitly describe the
correspondence, and give some examples.
