On the Rokhlin lemma for infinite measure-preserving bijections
Fabien Hoareau, François Le Maître
We study the Rokhlin lemma in the context of infinite measure-preserving bijections, and completely classify such bijections up to -approximate conjugacy, where is the infin…

On the stability of hyperbolicity under quantitative measure equivalence
Thiebout Delabie, Juhani Koivisto, François Le Maître +1
A well-known result of Shalom says that lattices in SO are measure equivalent for all . His proof actually yields the following stronger statement: the…

We show that some derived full groups provide examples of non simple Polish groups with the topological bounded normal generation property. In particular, it follows…
