Description
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.
