DESCRIPTION:Title: Action of the Cremona group on a CAT(0) cube complex.\n
 \nAbstract: The Cremona group is the group of birational transformations o
 f the projective plane. Even if this group comes from algebraic geometry\,
  tools from geometric group theory have been powerful to study it. In this
  talk\, based on a joint work with Christian Urech\, we will build a natur
 al action of the Cremona group on a CAT(0) cube complex. We will then expl
 ain how we can obtain new and old group theoretical and dynamical results 
 on the Cremona group.\n\n \n\nLink: https://mcgill.zoom.us/j/98910726246?p
