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…
