Coboundary expansion and Gromov hyperbolicity

open access: yesGroups, Geometry, and Dynamics
We prove that if a compact n -manifold admits a sequence of residual covers that form a coboundary expander in dimension  n-2 , then the manifold has Gromov ...

Detours and Gromov hyperbolicity

open access: yes, 2008
The notion of Gromov hyperbolicity was introduced by Gromov in the setting of geometric group theory [G1], [G2], but has played an increasing role in analysis on general metric spaces [BHK], [BS], [BBo], [BBu], and extendability of Lipschitz mappings [L].

Stability of Gromov hyperbolicity

open access: yes, 2010
A main problem when studying any mathematical property is to determine its stability, i.e., under what type of perturbations it is preserved. With this aim, here we study the stability of Gromov hyperbolicity, a property which has been proved to be fruitful in many fields.

Gromov hyperbolic in directed graphs

open access: yes, 2022
In this paper, we generalize the classical definition of Gromov hyperbolicity to the context of directed graphs and we extend one of the main results of the theory: the equivalence of the Gromov hyperbolicity and the geodesic stability. This theorem has potential applications to the development of solutions for secure data transfer on the internet.
