Contractible Rips complexes of groups via metric gluings

Kevin Li, Luis Jorge Sánchez Saldaña

We say that a finitely generated group equipped with a finite generating set is of type $R$ if the Rips complex is contractible for sufficiently large scales. We show that…

A note on higher coherence of graphs of groups

Kevin Li, Luis Jorge Sánchez Saldaña

For $n \in N$ , a group is called $n$ -coherent if every subgroup of type $F_{n}$ is of type $F_{n + 1}$ . For $n \geq 1$ , we observe that graphs of groups with $n…

Amenable covers of right-angled Artin groups

Kevin Li

Let $A_{L}$ be the right-angled Artin group associated to a finite flag complex $L$ . We show that the amenable category of $A_{L}$ equals the virtual cohomological dimension of the rig…
