Almost invariant CND kernels and proper uniformly Lipschitz actions on subspaces of $L^1$ by Vergara, Ignacio is a scholarly article available to read on EtoBox.

What is Almost invariant CND kernels and proper uniformly Lipschitz actions on subspaces of $L^1$ about?

We define the notion of almost invariant conditionally negative definite kernel and use it to give a characterisation of groups admitting a proper uniformly Lipschitz affine action on a subspace of an $L^1$ space. We show that this condition is satisfied by groups acting properly on products of quasi-trees, weakly amenable groups with Cowling-Haagerup constant 1, and a-TTT-menable groups.
