Title: Apery class and Gamma-conjectures

Date: September 15, 2011

Place: Bayreuth University

Abstract: I'll define a characteristic class of Fano variety (called Apery class) and conjecture its value in terms of Chern classes of variety and explicit constants (periods). This definition and conjectures is extension of previous works by Dubrovin, Golyshev, Iritani, Katzarkov-Kontsevich-Pantev, van Straten and others. If time permits I'll show how to prove it for some cases.
