Knot polynomials and knot homologies

POSTER

A knot polynomial is an invariant that assigns a polynomial to each knot in S^3. For a long time, only
one such invariant was known - the Alexander polynomial. In the early 80's the work of Jones, Witten,
Reshetikhin, and Turaev led to the systematic construction of many more knot polynomials.
In the last 20 years, there has been a great deal of research on "categorifying" these knot polynomials,
starting with Khovanov's famous categorification of the Jones polynomial.

In these lectures, I will first define some knot polynomials and give some of their classical
applications. Then, I'll explain some things about their categorifications, including Khovanov homology
and knot Floer homology, and give some applications of these as well.
