Wreath products with the integers, proper actions and Hilbert space compression

Yves Stalder, Alain Valette

We prove that the properties of acting metrically properly on some space with walls or some CAT(0) cube complex are closed by taking the wreath product with \Z. We also give a lowe…

Paul Jolissaint, Yves Stalder

Let $Γ$ be a countable group and let $Γ_{0}$ be an infinite abelian subgroup of $Γ$ . We prove that if the pair $(Γ, Γ_{0})$ satisfies some combinatorial condition called (SS), then the…
