Actions of right-angled Coxeter groups on CAT(0) spaces
Abstract: In this talk we discuss necessary and sufficient conditions for a
geometric action of a right-angled Coxeter group on a CAT(0) space to have
a strict fundamental domain. These conditions give insight into both the
group - in terms of rigidity and its automorphism group - as well as the
space.
