Title:  The Burau representation of the braid group

Abstract:   The Burau representation is a representation of the braid groups that was first defined and studied in the 1930's. It is an open question whether this representation is faithful for n=4. I will describe this representation in terms of covering spaces, discuss what is understood about the (non-)faithfulness of this representation for other n, and explain how the n=4 case is connected to the long-standing open problem in knot theory of whether the Jones polynomial is an unknot detector.
