Cari tutti, Il prossimo seminario di geometria algebrica e aritmetica di Pisa si terrà (purtroppo di nuovo) ONLINE il mercoledì 11 NOVEMBRE 2020 alle 18:00 Programma: Giulia Sacca’ (New York): Birational Geometry of the Intermediate Jacobian fibration Link al seminario: https://meet.google.com/mgr-ybkg-brj Abstract: I will start by presenting some applications of the minimal model program to the construction of symplectic compactifications of certain Lagrangian fibrations (integrable systems) of geometric origin. One such case is that of the intermediate Jacobian fibration associated to a cubic fourfold (Donagi-Markman integrable system). In the second part of the talk, I will discuss aspects of the birational geometry of this fibration (e.g. the Mordell-Weil group). Migliori saluti, Tamás Szamuely
