Abstract
This talk is based on joint work with John Christian Ottem. I will explain a generalization of results by Shinder on variation of stable birational types in degenerating families, and how this can be used to extend Schreieder’s non-stable rationality bounds from hypersurfaces to complete intersections in characteristic zero. This technique yields new results already for complete intersections of quadrics.
