Springer theory in braid groups and the Birman-Ko-Lee monoid
arXiv:math/0010254
Abstract
We state a conjecture about centralizers of certain roots of central elements in braid groups, and check it for Artin braid groups and some other cases. Our proof makes use of results by Birman-Ko-Lee; we give a new intrinsic account of these results.
