Conjugacy problem for braid groups and Garside groups. (English) Zbl 1043.20019

The authors present a new algorithm to solve the conjugacy problem in Artin braid groups, which is faster than the one presented by J. Birman, K. H. Ko and S. J. Lee [Adv. Math. 139, No. 2, 322-353 (1998; Zbl 0937.20016)]. This algorithm can be applied not only to braid groups, but to all Garside groups (which include finite type Artin groups and torus knot groups, among others).
