Commensurators of abelian subgroups in CAT(0) groups

Jingyin Huang, Tomasz Prytuła

We study the structure of the commensurator of a virtually abelian subgroup $H$ in $G$ , where $G$ acts properly on a $CAT (0)$ space $X$ . When $X$ is a Hadamard manifold an…

Bredon cohomological dimension for virtually abelian stabilisers for CAT(0) groups

Tomasz Prytuła

Given a discrete group $G$ , for any integer $r ⩾ 0$ we consider the family of all virtually abelian subgroups of $G$ of rank at most $r$ . We give an upper bound for the Bredo…
