Density of Metric Small Cancellation in Finitely Presented Groups [PDF]

open access: yesGroups, Complexity, Cryptology, 2020
Small cancellation groups form an interesting class with many desirable properties. It is a well-known fact that small cancellation groups are generic; however, all previously known results of their genericity are asymptotic and provide no information ...

Sub-Finsler Horofunction Boundaries of the Heisenberg Group

open access: yesAnalysis and Geometry in Metric Spaces, 2021
We give a complete analytic and geometric description of the horofunction boundary for polygonal sub-Finsler metrics, that is, those that arise as asymptotic cones of word metrics, on the Heisenberg group.

Packing subgroups in relatively hyperbolic groups [PDF]

open access: yes, 2006
Our main result establishes the bounded packing of relatively quasiconvex subgroups of a relatively hyperbolic group, under mild hypotheses. As an application, we prove that relatively quasiconvex subgroups have finite height and width, properties that ...

Hadamard spaces with isolated flats [PDF]

open access: yes, 2004
We explore the geometry of nonpositively curved spaces with isolated flats, and its consequences for groups that act properly discontinuously, cocompactly, and isometrically on such spaces.

On asymptotic dimension of groups [PDF]

open access: yes, 2000
We prove a version of the countable union theorem for asymp- totic dimension and we apply it to groups acting on asymptotically nite dimensional metric spaces. As a consequence we obtain the following nite dimensionality theorems.

Injectivity results for coarse homology theories

open access: yesProceedings of the London Mathematical Society, Volume 121, Issue 6, Page 1619-1684, December 2020., 2020
Abstract We show injectivity results for assembly maps using equivariant coarse homology theories with transfers. Our method is based on the descent principle and applies to a large class of linear groups or, more generally, groups with finite decomposition complexity.

The asymptotic geometry of right-angled Artin groups, I [PDF]

open access: yes, 2007
We study atomic right-angled Artin groups ‐ those whose defining graph has no cycles of length 4, and no separating vertices, separating edges, or separating vertex stars.

Non-positively curved complexes of groups and boundaries [PDF]

open access: yes, 2012
Given a complex of groups over a finite simplicial complex in the sense of Haefliger, we give conditions under which it is possible to build an EZ ‐structure in the sense of Farrell and Lafont for its fundamental group out of such structures for its ...

On group-theoretic models of randomness and genericity [PDF]

open access: yes, 2007
We compare Gromov's density model of random groups with the Arzhantseva- Ol'shanskii model of genericity. Mathematics Subject Classification (2000). 20F69; 20F65, 20E07.
