Action of the Cremona group on a CAT(0) cube complex

Appears in collection : Virtual Geometric Group Theory conference / Rencontre virtuelle en géométrie des groupes

The Cremona group is the group of birational transformations of 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 natural action of the Cremona group on a CAT(0) cube complex. We will then explain how we can obtain new and old group theoretical and dynamical results on the Cremona group.
