Title: On connected algebraic subgroups of Bir(X)
Abstract: The problem of understanding the structure of the group of birational transformations Bir(X) of a projective variety X is an old one, dating all the way back to the 19th century.In general Bir(X) does not admit the structure of an algebraic group; however one may study algebraic subgroups of it and how they relate to one another. In the last decade there has been a resurgence of results in this area, mainly due to the use of the modern machinery of the Minimal Model Program and the Sarkisov Program.In this talk I will present this modern framework as well as various results around the study of algebraic subgroups of Bir(X) for a Mori fiber space X.
