Fibred coarse embeddability of box spaces and proper isometric affine actions on spaces

Sylvain Arnt

We show the necessary part of the following theorem : a finitely generated, residually finite group has property (i.e. it admits a proper isometric affine action on some $L^…

The Haagerup property is not invariant under quasi-isometry

Mathieu Carette, Kevin Whyte, Sylvain Arnt +2

Using the work of Cornulier-Valette and Whyte (see Appendix A for the latter), we show that neither the Haagerup property nor weak amenability is invariant under quasi-isometry of…

Spaces with labelled partitions and isometric affine actions on Banach spaces

Sylvain Arnt

We define the structure of spaces with labelled partitions which generalizes the structure of spaces with measured walls and study the link between actions by automorphisms on spac…
