摘要
We classify an action of the n-strand braid group on the free group of rank n, which is similar to the Artin representation in the sense that the ith generator sigma(i) of B-n acts so that it fixes all free generators x(j) except j = i, i + 1. We determine all such representations and discuss knot invariants coming from such representations.
