Emanuel Scheidegger:
Pencils of cubic fourfolds
Zeit und Ort
Freitag, 20.1.12, 10:00-11:00, Raum 404, Eckerstr. 1
Zusammenfassung
We will discuss some Hodge-theoretic aspects of families of cubic fourfolds. Our focus will lie on so-called special cubic fourfolds, which contain an algebraic surface not homologous to a plane. We will show that there is a modular form that counts the special members of a pencil of cubic fourfolds. If time permits, we will go on with some speculations on the derived category of special cubic fourfolds and homological mirror symmetry.
