We prove foundational results for homological Dehn functions of groups of type $FP_2$ such as superadditivity and the invariance under quasi-isometry. We then study the homological Dehn functions of Leary's groups $G_L(S)$ providing methods to obtain uncountably many groups with a given homological Dehn function. This allows us to show that there exist groups of type $FP_2$ with quartic homological Dehn function and unsolvable word problem.

Dehn functions of coabelian subgroups of direct products of groups
• Mathematics

We develop new methods for computing the precise Dehn functions of coabelian subgroups of direct products of groups, that is, subgroups which arise as kernels of homomorphisms from the direct product

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

On Dehn functions and products of groups
If G is a finitely presented group then its Dehn function ― or its isoperimetric inequality ― is of interest. For example, G satisfies a linear isoperimetric inequality iff G is negatively curved (or
Uncountably many quasi-isometry classes of groups of type FP
• Mathematics

Abstract:In an earlier paper, one of the authors constructed uncountable families of groups of type $FP$ and of $n$-dimensional Poincar\\'e duality groups for each $n\\geq 4$. We show that those
Uncountably many groups of type FP
We construct uncountably many discrete groups of type FP; in particular we construct groups of type FP that do not embed in any finitely presented group. We compute the ordinary, ℓ2 , and compactly
Subgroups of relatively hyperbolic groups of Bredon cohomological dimension 2
Abstract A remarkable result of Gersten states that the class of hyperbolic groups of cohomological dimension 2 is closed under taking finitely presented (or more generally FP 2 {\mathrm{FP}_{2}} )
A Subgroup Theorem for Homological Filling Functions

We use algebraic techniques to study homological filling functions of groups and their subgroups. If $G$ is a group admitting a finite $(n+1)$--dimensional $K(G,1)$ and $H \leq G$ is of type

Homological and homotopical Dehn functions are different

Proceedings of the National Academy of Sciences

The homological and homotopical Dehn functions are different ways of measuring the difficulty of filling a closed curve inside a group or a space. The homological Dehn function measures fillings of

We use basic tools of descriptive set theory to prove that a closed set S of marked groups has 2ℵ0 quasi‐isometry classes, provided that every non‐empty open subset of S contains at least two
Minimal presentations of groups
This thesis proposes two new families of counterexamples to the celebrated relation gap problem: firstly certain finite-index subgroups of right-angled Artin groups, and secondly groups with torsion
On Dehn functions of free products of groups
• Mathematics
• 1999
In this article we show that the Dehn function of a nontrivial free product of groups is equivalent to its subnegative closure. Let P = 〈Σ | R 〉 be a finite presentation of a group G. Suppose that a
