Given a morphism φ : G → AoB from a finitely presented group G to a wreath product A o B, we show that, if the image of φ is a sufficiently large subgroup, then ker(φ) contains a non-abelian free subgroup and φ factors through an acylindrically hyperbolic quotient of G. As direct applications, we classify the finitely presented subgroups in A o B up to isomorphism and we deduce that a group having a wreath product (non-trivial) o (infinite) as a quotient must be SQ-universal (extending theorems…

Asymptotically rigid mapping class groups II: strand diagrams and nonpositive curvature
In this article, we introduce a new family of groups, called Chambord groups and constructed from braided strand diagrams associated to specific semigroup presentations. It includes the

Finitely Presented Wreath Products and Double Coset Decompositions
We characterize which permutational wreath products $$G \ltimes W^{(X)}$$ are finitely presented. This occurs if and only if G and W are finitely presented, G acts on X with finitely generated
On Property (FA) for wreath products
Abstract We characterize permutational wreath products with Property (FA). For instance, we show that the standard wreath product A ≀ B of two non-trivial countable groups A and B has Property (FA)
Acylindrical hyperbolicity from actions on CAT(0) cube complexes: a few criteria
The question which motivates the article is the following: given a group acting on a CAT(0) cube complex, how can we prove that it is acylindrically hyperbolic? Keeping this goal in mind, we show a
Automorphisms of graph products of groups and acylindrical hyperbolicity.
This article is dedicated to the study of the acylindrical hyperbolicity of automorphism groups of graph products of groups. Our main result is that, if $\Gamma$ is a finite graph which contains at
Hyperbolic and cubical rigidities of Thompson’s group V
Abstract In this article, we state and prove a general criterion allowing us to show that some groups are hyperbolically elementary, meaning that every isometric action of one of these groups on a
Tits alternatives for graph products
We discuss various types of Tits Alternative for subgroups of graph products of groups, and prove that, under some natural conditions, a graph product of groups satisfies a given form of Tits
The algebraic structure of group rings
There appeared in 1976 an expository paper by the present author [52] entitled "What is a group ringV This question, rhetorical as it is, may nevertheless be answered directly by saying that for a
Automorphisms of graph products of groups from a geometric perspective
This article studies automorphism groups of graph products of arbitrary groups. We completely characterise automorphisms that preserve the set of conjugacy classes of vertex groups as those
Asymptotic geometry of lamplighters over one-ended groups
This article is dedicated to the asymptotic geometry of wreath products F oH := (⊕ H F ) oH where F is a finite group and H a one-ended finitely presented group. Our main result is a complete
Acylindrical hyperbolicity of groups acting on trees
We provide new examples of acylindrically hyperbolic groups arising from actions on simplicial trees. In particular, we consider amalgamated products and HNN-extensions, one-relator groups,
