DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ZAG/167/">Ac
 tions of Cremona groups on CAT(0) cube complexes</a>\nby Christian Urech (
 École polytechnique fédérale de Lausanne) as part of ZAG (Zoom Algebrai
 c Geometry) seminar\n\n\nAbstract\nRecently\, in geometric group theory\, 
 isometric actions of groups on CAT(0) cube complexes have turned out to be
  powerful tools to study a broad range of groups. In this talk\, I will ex
 plain the construction of CAT(0) cube complexes on which groups of biratio
 nal transformations act by isometries and explain how to use these actions
  to deduce new and old group theoretical and dynamical results about Cremo
 na groups. This is joint work with Anne Lonjou.\n
