DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGOON/25/">
 Birationality centers\, rationality problems and Cremona groups</a>\nby Ev
 geny Shinder (University of Sheffield\, UK) as part of Longitudinal Algebr
 a and Geometry Open ONline Seminar (LAGOON)\n\n\nAbstract\nI will introduc
 e a framework to account for the ambiguity of stable birational types of a
  sequence of centers for birational transformations. I will explain in whi
 ch settings the introduced invariants are nonvanishing\, and give applicat
 ions to the structure of Cremona groups over various fields. This is joint
  work in progress with Hsueh-Yung Lin and Susanna Zimmermann.\n\nMeeting L
