The Noether-Lefschetz conjecture and generalizations
Nicolas Bergeron, Zhiyuan Li, John Millson +1
We prove the Noether-Lefschetz conjecture on the moduli space of quasi-polarized K3 surfaces. This is deduced as a particular case of a general theorem that states that low degree…

Picard groups on moduli of K3 surfaces with Mukai models
Francois Greer, Zhiyuan Li, Zhiyu Tian
We discuss the Picard group of moduli space of quasi-polarized K3 surfaces of genus and . In this range, is unirational and a g…

Integral Hodge classes on fourfolds fiberd by quadric bundles
Zhiyuan Li, Zhiyu Tian
We discuss the space of sections and certain bisections on a quadric surfaces bundle over a smooth curve. The Abel-Jacobi from these spaces to the intermediate Jacobian will be…
