Titolo: Rationally connected threefolds with nef anticanonical divisor
Quando: 15/11/2021 - 11:00
Dove: Palazzo Campana - TORINO
Aula: Sala Orsi e Aula Virtuale Webex
Relatore: Zhixin Xie
Afferenza: Université Côte d'Azur
Locandina: Locandina

Descrizione:

Abstract : Complex projective varieties with nef anticanonical divisor appear as natural generalisations of Fano varieties. Fano manifolds are classified up to dimension three and many of their properties are well studied. However, the classification of manifolds with nef anticanonical divisor is more complicated as new phenomena arise and many results for Fano manifolds no longer hold for this class of varieties. In this talk, we will first look at some examples in dimension two. Then we will discuss some properties of rationally connected threefolds with nef anticanonical divisor. We will consider the case where the anticanonical divisor is not semi-ample, and will give a classification result in this case.
