Nasjonalt algebramøte 2018: Eugenia Ferrari

Eugenia Ferrari, UiB: Birational invariants characterising abelian varieties.

Abstract:  At the beginning of the XX century Enriques proved that a 
smooth complex surface with first and fourth plurigenus equal to 1 and 
irregularity equal to 2 is birationally equivalent to an abelian 
surface. In this talk I will sketch out how Enriques’ theorem has been 
extended to higher dimension and to positive characteristic. In 
particular, I will discuss a first result I obtained as part of my PhD 
project: a version of Enriques’ theorem for surfaces in characteristic
