Evento

Titolo: Fano varieties in Mori fibre spaces
Quando: 18/05/2016 - 15:30
Dove: Palazzo Campana - TORINO
Aula: Aula C
Relatore: Giulio Codogni
Afferenza: Università di Roma Tre
Locandina: Locandina

Descrizione:

We show that being a general fibre of a Mori fibre space is a rather restrictive condition for a Fano variety. More specifically, we obtain two criteria (one sufficient and one necessary) for a Q-factorial Fano variety with terminal singularities to be realised as a fibre of a Mori fibre space, which turn into a characterisation in the rigid case. We apply our criteria to figure out this property up to dimension three and on rational homogeneous spaces. The smooth toric case is studied and an interesting connection with K-semistability is also investigated. This is a joint work with A. Fanelli, L. Tasin and R. Svaldi; it started during the summer school Pragmatic 2013.
