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. 

Superexponential Dehn functions inside CAT(0) groups

We construct 4–dimensional CAT(0) groups containing finitely presented subgroups whose Dehn functions are exp(x) for integers n,m ≥ 1 and 6–dimensional CAT(0) groups containing finitely presented

Some New CAT(0) Free-by-Cyclic Groups

We show the existence of several new infinite families of polynomially-growing automorphisms of free groups whose mapping tori are CAT(0) free-by-cyclic groups. Such mapping tori are thick, and thus

Bestvina--Brady Groups with Polynomial Dehn Functions

Let $\Gamma$ be a finite simplicial graph that contains no induced $K_{4}$ subgraphs. We show that with some assumptions, the Dehn function of the associated Bestvina--Brady group is polynomial.

Dehn functions of mapping tori of right-angled Artin groups.

The algebraic mapping torus $M_{\Phi}$ of a group $G$ with an automorphism $\Phi$ is the HNN-extension of $G$ in which conjugation by the stable letter performs $\Phi$. We classify the Dehn functions

Identifying Dehn functions of Bestvina–Brady groups from their defining graphs

Let $$\Gamma $$ be a finite simplicial graph such that the flag complex on $$\Gamma $$ is a 2-dimensional triangulated disk. We show that with some assumptions, the Dehn function of the associated

Dehn Functions of Bestvina-Brady Groups

In this dissertation, we prove that if the flag complex on a finite simplicial graph is a 2-dimensional triangulated disk, then the Dehn function of the associated Bestvina–Brady group depends on the


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.

Train Tracks on Graphs of Groups and Outer Automorphisms of Hyperbolic Groups

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


My research area is geometric group theory, which is the study of infinite discrete groups through their actions on metric spaces. Historically, groups arise from geometry. In 1872, F. Klein wanted



On the Subgroups of Right Angled Artin Groups and Mapping Class Groups

There exist right angled Artin groups $A$ such that the isomorphism problem for finitely presented subgroups of $A$ is unsolvable, and for certain finitely presented subgroups the conjugacy and

Minimal dimension faithful linear representations of common finitely presented groups

For various finitely presented groups, including right angled Artin groups and free by cyclic groups, we investigate what is the smallest dimension of a faithful linear representation. This is done

Morse theory and finiteness properties of groups

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.

Detecting the growth of free group automorphisms by their action on the homology of subgroups of finite index

We prove that if F is a finitely generated free group and f:F -> F is an automorphism with polynomial growth of degree d, then there exists a characteristic subgroup S < F of finite index such that

Isoperimetric inequalities for the fundamental groups of torus bundles over the circle

We give upper bounds for isoperimetric functions of semi-direct products in terms of the asymptotic behaviour of ||Ak|| ask → ∞. In the caseA ∈ Sp(n, ℤ) we show that these bounds are sharp. This

It is shown that groups in this class of linear groups that do not contain unipotent elements of infinite order have good closure properties, in addition to having properties akin to non-positive curvature, which were proved in [6].

Cubulating hyperbolic free-by-cyclic groups: The irreducible case

Let $V$ be a finite graph and let $\phi:V\rightarrow V$ be an irreducible train track map whose mapping torus has word-hyperbolic fundamental group $G$. Then $G$ acts freely and cocompactly on a

An isoperimetric function for Bestvina–Brady groups

Given a right‐angled Artin group A, the associated Bestvina–Brady group is defined to be the kernel of the homomorphism A → ℤ that maps each generator in the standard presentation of A to a fixed

Cubular tubular groups

. Let G split as a finite graph of free abelian groups with cyclic edge groups. We characterize when G acts freely on a CAT(0) cube complex. We show that if G acts properly and semi-simply on a CAT(0)

Cubulating hyperbolic free-by-cyclic groups: the general case

Let $${\Phi\colon F\rightarrow F}$$Φ:F→F be an automorphism of the finite-rank free group F. Suppose that $${G=F\rtimes_\Phi\mathbb{Z}}$$G=F⋊ΦZ is word-hyperbolic. Then G acts freely and cocompactly
