The n-th root of a braid is unique up to conjugacy

Geometric Topology 2014-10-01 v2 Group Theory

Abstract

We prove a conjecture due to Makanin: if a and b are elements of the Artin braid group B_n such that a^k=b^k for some nonzero integer k, then a and b are conjugate. The proof involves the Nielsen-Thurston classification of braids.
