Higher signs for Coxeter groups

Zhiwei Yun

Published 2019-08-10Version 1

We define and study cocycles on a Coxeter group in each degree generalizing the sign function. When the Coxeter group is a Weyl group, we explain how the degree three cocycle arises naturally from geometry representation theory.
