Computation of Centralizers in Braid groups and Garside groups

Given a group G,thecentralizer ,of an element, a ∈ G, denoted Z(a), is the subgroup of G consisting of all elements which commute with a. Our goal in this paper is to give a good algorithm to compute a generating set for the ,centralizer of an element, in a Garside group. Garside groups were introduced by Dehornoy and Paris [7] (their original

Generalities on Central Simple Algebras

Let Dbe the ,centralizer, of Ain the k-algebra End k(S):By the double ,centralizer, theorem, A= C(D);i.e. A= End D(S): But Sis a simple A-module. Thus for d2Dmultiplication by dis an A-linear endomorphism d: S!Sand hence is either 0 or invertible, by Schur’s Lemma. Since the inverse is also A-linear and D= C(A);it follows that Dis a division algebra.
