Del Pezzo fibrations in positive characteristic

Andrea Fanelli (University of Bordeaux)

Wednesday 17th February 16:00-17:00 online (zoom)

Abstract

In this talk, I will discuss some pathologies for the  generic fibre of del Pezzo fibrations in characteristic p>0, motivated by the recent developments of the MMP in positive  characteristic. The recent joint work with Stefan Schröer applies to deduce information on the structure of 3-dimensional Mori fibre spaces and answers an old question by János Kollár.
