PROPER ACTIONS OF WREATH PRODUCTS AND GENERALIZATIONS
We study stability properties of the Haagerup property and of coarse embeddability in a Hilbert space, under certain semidirect products. In particular, we prove that they are stable under takingExpand

Isometric Group Actions on Hilbert Spaces: Growth of Cocycles
Abstract.We study growth of 1-cocycles of locally compact groups, with values in unitary representations. Discussing the existence of 1-cocycles with linear growth, we obtain the followingExpand
