Birationality Centers and Cremona Groups
Evgeny Shinder (University of Sheffield)

Abstract:

I will introduce a framework to account for the ambiguity of stable birational types of a sequence of centers for birational transformations. I will explain in which settings the introduced invariants are nonvanishing, and give applications to the structure of Cremona groups over various fields (based on joint work in progress with H.-Y. Lin and S. Zimmermann).
