In this paper, the notion of proper proximality (introduced in [BIP18]) is studied for various families of groups that act on trees. We show that if a group acts nonelementarily by isometries on a tree such that for any two edges, the intersection of their edge stabilizers is finite, then G is properly proximal. We then provide a complete classification result for proper proximality among graph products of non-trivial groups, generalizing recent work of Duchesne, Tucker-Drob and Wesolek… Expand

This paper shows that graph products of weakly amenable discrete groups are weaklyAmenable (with Cowling-Haagerup constant 1) and constructs a wall space associated to the word length structure of a graph product and gives a method for extending completely bounded functions on discrete groups to a completely bounded function on their graph product.

Properly proximal groups and their von Neumann algebras
We introduce a wide class of countable groups, called properly proximal, which contains all non-amenable bi-exact groups, all non-elementary convergence groups, and all lattices in non-compactExpand
CAT(0) cube complexes and inner amenability
We here consider inner amenability from a geometric and group theoretical perspective. We prove that for every non-elementary action of a group $G$ on a finite dimensional irreducible CAT(0) cubeExpand

In the 1970's Baudisch introduced the idea of the semifree group, that is, a group in which the only relators are commutators of generators. Baudisch was mainly concerned with subgroup problems,Expand
When is the graph product of hyperbolic groups hyperbolic?
Given a finite simplicial graph ℊ, and an assignment of groups to the verticles of ℊ, the graph product is the free product of the vertex groups modulo relations implying that adjacent vertex groupsExpand
Random Walks and Boundaries of CAT(0) Cubical complexes
We show under weak hypotheses that the pushforward $\{Z_no\}$ of a random-walk to a CAT(0) cube complex converges to a point on the boundary. We introduce the notion of squeezing points, which allowsExpand

This paper defines the boundary of a relatively hyperbolic group, and shows that the limit set of any geometrically finite action of the group is equivariantly homeomorphic to this boundary, and generalizes a result of Tukia for geometRically finite kleinian groups. Expand
Combination of convergence groups
We state and prove a combination theorem for relatively hyperbolic groups seen as geometrically finite convergence groups. For that, we explain how to contruct a boundary for a group that is anExpand
Boundaries of graphs of relatively hyperbolic groups with cyclic edge groups
We prove that the fundamental group of a finite graph of convergence groups with parabolic edge groups is a convergence group. Using this result, under some mild assumptions, we prove combinationExpand
