Title: The Centralizer of a Coxeter Element
Abstract:
A classical result in finite Coxeter groups states that the centralizer of a Coxeter element is the cyclic group generated by this Coxeter element. We generalize this result to infinite Coxeter groups by using results on outward roots and straight elements. This is joint work with Ruwen Hollenbach.
