Abstract

There are some interesting connections between the theory of algebraic functions and Artin’s theory of braids. For instance, the space G n of polynomials of degree n not having multiple roots is the space K(π ,1) for the group B(n) of braids with n strings:

π1(G n ) = B(n), π i (G n ) = 0 for i > 1. (1)
