Strong Property (T), weak amenability and $ℓ^{p}$ -cohomology in $A ~_{2}$ -buildings

Jean Lécureux, Mikael de la Salle, Stefan Witzel

We prove that cocompact (and more generally: undistorted) lattices on $A ~_{2}$ -buildings satisfy Lafforgue's strong property (T), thus exhibiting the first examples that are n…

Proper proximality in non-positive curvature

Camille Horbez, Jingyin Huang, Jean Lécureux

Proper proximality of a countable group is a notion that was introduced by Boutonnet, Ioana and Peterson as a tool to study rigidity properties of certain von Neumann algebras asso…
