Asymptotic dimension

G Bell, A Dranishnikov - Topology and its Applications, 2008 - Elsevier
The asymptotic dimension theory was founded by Gromov [M. Gromov, Asymptotic invariants
of infinite groups, in: Geometric Group Theory, vol. 2, Sussex, 1991, in: London Math. Soc …

A notion of geometric complexity and its application to topological rigidity

E Guentner, R Tessera, G Yu - Inventiones mathematicae, 2012 - Springer
We introduce a geometric invariant, called finite decomposition complexity (FDC), to study
topological rigidity of manifolds. We prove for instance that if the fundamental group of a …

A Hurewicz theorem for the Assouad–Nagata dimension

N Brodskiy, J Dydak, M Levin… - Journal of the London …, 2008 - academic.oup.com
Given a function f: X→ Y of metric spaces, the classical Hurewicz theorem states that dim
(X)≤ dim (f)+ dim (Y). We provide analogs of this theorem for the Assouad–Nagata …

Discrete groups with finite decomposition complexity

EW Guentner, R Tessera, G Yu - Groups, Geometry, and Dynamics, 2013 - ems.press
In an earlier work we introduced a geometric invariant, called finite decomposition
complexity (FDC), to study topological rigidity of manifolds. In particular, we proved the …

Configuration Lie groupoids and orbifold braid groups

SK Roushon - Bulletin des Sciences Mathématiques, 2021 - Elsevier
We propose two definitions of configuration Lie groupoids and in both the cases we prove a
Fadell-Neuwirth type fibration theorem for a class of Lie groupoids. We show that this is the …

Foundations of geometric approximate group theory

M Cordes, T Hartnick, V Tonić - arXiv preprint arXiv:2012.15303, 2020 - arxiv.org
We develop the foundations of a geometric theory of countably-infinite approximate groups,
extending work of Bj\" orklund and the second-named author. Our theory is based on the …

[HTML][HTML] Some categorical aspects of coarse spaces and balleans

D Dikranjan, N Zava - Topology and its Applications, 2017 - Elsevier
Abstract Coarse spaces [26] and balleans [23] are known to be equivalent constructions
([25]). The main subject of this paper is the category, Coarse, having as objects these …

Quantitative measure equivalence between amenable groups

T Delabie, J Koivisto, F Le Maître… - Annales Henri …, 2022 - numdam.org
We initiate a quantitative study of measure equivalence (and orbit equivalence) between
finitely generated groups, which extends the classical setting of Lp measure equivalence. In …

Permanence in coarse geometry

E Guentner - Recent Progress in General Topology III, 2013 - Springer
The, large scale, or coarse perspective on the geometry of metric spaces plays an important
role in approaches to conjectures in operator algebras and the topology of manifolds …
