Ciao a tutti,
vi ricordiamo che domani Martedì 16 aprile, alle 16:30-17:30 in Aula Riunioni del dip. mat.
ci sarà il seminario dei baby-geometri:
- speaker: Daniele Celoria (Università di Firenze) - Titolo: "Rational blowdown of elliptic surfaces" - Abstract: We introduce elliptic fibrations from a topological point of view, together with some of the most common operations that can be performed on them. After a quick review of the Seiberg-Witten invariants, we define rational blowdowns and use them to exhibit infinite families of exotic elliptic fibrations.
