Visible Artin Subgroups of Right-Angled Coxeter Groups

LaForge, Garret.


  • Abstract: We consider an extension of work done by Michael Davis and Tadeusz Januszkiewicz in 1999. Given a right-angled Artin group A, they showed how to construct a right-angled Coxeter group W in which A sits as a subgroup of finite index. We partially classify the RACGs W which admit such an embedding, obtaining complete results when W is hyperbolic, virtually free, or 1-ended. We introduce th... read more
