Schedule:

9:00-10:00 Shunsuke Takagi: A Gorenstein criterion for strongly F-regular and log terminal singularities

Abstract: Let (X, x) be a normal F-pure (resp. log canonical) singularity. We give a criterion for (X, x) to be quasi-Gorenstein in terms of an F-pure (resp. log canonical) threshold under the hypothesis that its anti-canonical cover is finitely generated.

10:00-10:30 break

10:30-11:30 Zhiyuan Li: Cones and tautological classes on moduli of K3 surfaces

Abstract: In this lecture, I will review the cycle theory on moduli problems. In particular, I will talk about the recent questions for cycles on moduli space of K3 surfaces. This includes the Noether-Lefschetz (NL) conjecture, the effective cone question and the tautological conjecture.

11:30-12:30 lunch

12:30-13:30 Don Zagier: Teichmueller curves and twisted modular forms

Abstract: TBA.
