Torsion groups do not act on $2$ -dimensional $CAT (0)$ complexes

Sergey Norin, Damian Osajda, Piotr Przytycki

We show, under mild hypotheses, that if each element of a finitely generated group acting on a $2$ -dimensional $CAT (0)$ complex has a fixed point, then there is a global f…

Virtually Fibering Right-Angled Coxeter Groups

Kasia Jankiewicz, Sergey Norin, Daniel T. Wise

We show that certain right-angled Coxeter groups have finite index subgroups that quotient to $Z$ with finitely generated kernels. The proof uses Bestvina-Brady Morse theor…
