XXL type Artin groups are CAT(0) and acylindrically hyperbolic

Thomas Haettel

We describe a simple locally CAT(0) classifying space for extra extra large type Artin groups (with all labels at least 5). Furthermore, when the Artin group is not dihedral, we de…

Tangent bundles of hyperbolic spaces and proper affine actions on $L^{p}$ spaces

Indira Chatterji, François Dahmani, Thomas Haettel +1

We define the notion of a negatively curved tangent bundle of a metric measured space. We prove that, when a group $G$ acts on a metric measured space $X$ with a negatively curved…
