Representations of braid groups


Speaker: Stephen Bigelow, University of California, Berkeley

Braid groups were originally defined by Artin as a tool for studying knots. A braid is a certain kind of arrangement of pieces of string in space. Two braids with the same number of strands can be multiplied by sticking their ends together. I will describe some homomorphisms from groups of braids to groups of matrices, and outline my proof that one such homomorphism is one-to-one.
