Course description and aims

The Alexander polynomial is a basic tool in the study of knots. In this course we study the twisted Alexander polynomial, which is a generalization of the Alexander polynomial. We define the Alexander polynomial using the free differential of the fundamental group of the knot complement. It can be generalized by applying a linear representation of the fundamental group. I will explain that the twisted Alexander polynomial may be regarded as a matrix-weighted zeta function of a graph. The colored Jones polynomial also can be obtained from the graph, then I will introduce the recent topics on the volume of a knot complement.

We learn basic methods in knot theory. We understand the Alexander polynomial and the Jones polynomial, and then study some applications.
