DESCRIPTION:Title: The infinite dimensional hyperbolic space of the Cremona
  group\n\nAbstract:\n\nIn recent years one of the main tool in the study o
 f the Cremona group is an action on an infinite dimensional hyperbolic spa
 ce. In particular this was the key to get a Tits alternative for this grou
 p\, and also for a proof of the non simplicity. My aim in this talk will b
 e to give a gentle introduction to this construction\, which relies on the
  notion of blowing-up a point in an algebraic surface (infinitely many tim
 es!).\n
