Quasi-isometric rigidity of a class of right-angled Coxeter groups · arXivDeskAbstract
We establish quasi-isometric rigidity for a class of right-angled Coxeter groups. Let Γ1,Γ2 be joins of finite generalized thick m-gons with m≥3
. We show that the corresponding right-angled Coxeter groups are quasi-isometric if and only if
are isomorphic. We also give a construction of commensurable right-angled Coxeter groups.
