# Dehn functions of subgroups of right-angled Artin groups

@article{Brady2018DehnFO, title={Dehn functions of subgroups of right-angled Artin groups}, author={Noel Brady and Ignat Soroko}, journal={Geometriae Dedicata}, year={2018}, volume={200}, pages={197-239} }

We show that for each positive integer k there exist right-angled Artin groups containing free-by-cyclic subgroups whose monodromy automorphisms grow as $$n^k$$nk. As a consequence we produce examples of right-angled Artin groups containing finitely presented subgroups whose Dehn functions grow as $$n^{k+2}$$nk+2.

If a group embeds into a right-angled Artin group, it has certain nice properties, such as linearity over Z, for example. There is a specifically remarkable class of subgroups of right-angled Artin…

It is shown that a tubular group is always virtually special (meaning that it has a finite index subgroup embedding in a RAAG) if the underlying graph is a tree.

Stallings remarked that an outer automorphism of a free group may be thought of as a subdivision of a graph followed by a sequence of folds. In this thesis, we prove that automorphisms of fundamental…

Abstract. We examine the finiteness properties of certain subgroups of “right angled” Artin groups. In particular, we find an example of a group that is of type FP(Z) but is not finitely presented.
