Variants of a-T-menability for actions on non-commutative Lp spaces

Baptiste Olivier

We investigate various characterizations of the Haagerup property (H) for a second countable locally compact group G, in terms of orthogonal representations of G on non-commutative…

Property (T) with respect to non-commutative Lp-spaces

Baptiste Olivier

We show that a group with Kazhdan's property $(T)$ has property $(T_{B})$ for $B$ the Haagerup non-commutative $L_{p} (M)$ -space associated with a von Neumann algebra $\ma…
