RAAGedy right-angled Coxeter groups

Christopher H. Cashen, Pallavi Dani, Alexandra Edletzberger +1

We give criteria for deciding whether or not a triangle-free simple graph is the presentation graph of a right-angled Coxeter group that is quasiisometric to some right-angled Arti…

RAAGedy right-angled Coxeter groups II: in the quasiisometry class of the tree RAAGs

Christopher H. Cashen

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 Co…

Cogrowth for group actions with strongly contracting elements

Goulnara N. Arzhantseva, Christopher H. Cashen

Let $G$ be a group acting properly by isometries and with a strongly contracting element on a geodesic metric space. Let $N$ be an infinite normal subgroup of $G$ , and let $δ_{N}$ an…
