Title: On degenerations of plane Cremona transformations.
Abstract: "I will present the group of Cremona transformations of the plane and the natural topology we can put on it. The set of maps of some bounded degree is closed, and the natural question that arises is to determine which maps of small degree are limits of maps of higher degree. I will give some answers to this question. This is a joint work with Alberto Calabri."
