RAAGedy right-angled Coxeter groups II: in the quasiisometry class of the tree RAAGs
arXiv:2504.06911 · doi:10.1090/proc/17393
Abstract
We classify two-dimensional right-angled Coxeter groups that are quasiisometric to a right-angled Artin group defined by a tree, and show that when this is true the right-angled Coxeter group actually contains a visible finite index right-angled Artin subgroup.
