In this talk I define the braid groups, its Garside structure, and its
application to solve the word and conjugacy problems. I present a braid
group with $n$ strands as the mapping class group of the disk with $n$
punctures, $\mathbb{D}^2-\{p_1\ldots p_n\}$, and a classification of
surface homeomorphisms by the Nielsen Thurston theorem. I will also
discuss results that require algebraic and geometric tools.

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.
