Variation of stable birational type and bounds for complete intersections

Moduli and Algebraic Cycles

02 September 14:30 - 15:30

Johannes Nicaise - Imperial College London

This talk is based on joint work with John Christian Ottem. I will explain a generalization of results by Shinder and Voisin 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 yields new results already for complete intersections of quadrics.
