Cyclic orders and actions of Leary--Minasyan groups on coarse $PD (n)$ spaces

Arka Banerjee, Kevin Schreve

We show that for $n \geq 3$ , there are torsion-free CAT(0) groups with visual boundaries that embed into $S^{n}$ but which are not virtually the fundamental group of a compact aspher…

On the Girth of Groups acting on CAT(0) cube complexes

Arka Banerjee, Daniel Gulbrandsen, Pratyush Mishra +1

We obtain a sufficient condition for lattices in the automorphism group of a finite dimensional CAT(0) cube complex to have infinite girth. As a corollary, we get a version of Girt…
