Cell structure of mediangle graphs

Victor Chepoi, Anthony Genevois, Kolja Knauer

Mediangle graphs are a common generalization of median graphs (1-sekeleta of CAT(0) cube complexes) and Coxeter graphs (Cayley graphs of Coxeter systems). Answering a question moti…

Polynomial hyperbolicity and products of free groups

Anthony Genevois

In this article, we define a locally finite graph as -polynomially hyperbolic if there exists a Lipschitz map to some hyperbolic space satisfying the foll…

Relative numbers of ends and quasi-median graphs

Anthony Genevois

Given a finitely generated and a subgraph , the relative number of ends is the number of ends of a Schreier graph and the number of coend…

Virtual splittings of right-angled Artin groups

Oussama Bensaid, Anthony Genevois, Romain Tessera

In this article, we determine, given a finite graph and an integer , when a right-angled Artin group virtually splits over an abelian subgroup of rank . M…

Coarse separation and splittings in right-angled Artin groups

Oussama Bensaid, Anthony Genevois, Romain Tessera

In this article, we characterise geometrically when a right-angled Artin group splits over an abelian subgroup. More precisely, given a finite graph , we show that spli…

Coarse separation and splittings in hyperbolic groups

Oussama Bensaid, Anthony Genevois, Romain Tessera

We study coarse separation in one-ended hyperbolic groups from a quantitative point of view, focusing on the volume growth of separating subsets. We prove that a one-ended hyperbol…
