On Kahler extensions of abelian groups
Corey Bregman, Letao Zhang
We show that any Kahler extension of a finitely generated abelian group by a surface group of genus g at least 2 is virtually a product. Conversely, we prove that any homomorphism…
Weak Approximation for Cubic Hypersurfaces and Degree 4 del Pezzo Surfaces
Letao Zhang, Zhiyu Tian
In this article we prove the following theorems about weak approximation of smooth cubic hypersurfaces and del Pezzo surfaces of degree 4 defined over global fields. (1) For cubic…
Character Formulas on Cohomology of Deformations of Hilbert Schemes of K3 Surfaces
Letao Zhang
Let X be a hyperkahler manifold deformation equivalent to a Hilbert scheme of n points on a K3 surface. We compute the graded character formula of the generic Mumford-Tate group r…
Modular Forms and Special Cubic Fourfolds
Zhiyuan Li, Letao Zhang
We study the degree of the special cubic fourfolds in the Hilbert scheme of cubic fourfolds via a computation of the generating series of Heegner divisors of even lattice of signat…
