$\mathrm{CAT}(0)$ Extensions of Right-angled Coxeter Groups
Published 21 Aug 2015 in math.GR | (1508.05403v1)
Abstract: We show that any split extension of a right-angled Coxeter group $W_{\Gamma}$ by a generating automorphism of finite order acts faithfully and geometrically on a $\mathrm{CAT}(0)$ metric space.
