具有指定霍奇数的几何霍奇结构

Geometric Hodge structures with prescribed Hodge numbers

Donu Arapura

摘要:

称一个纯霍奇结构为几何的,如果它包含在一个光滑复射影簇的上同调中。主要目的是证明对于任何一组霍奇数(受明显的约束),都存在一个几何霍奇结构,正好是这些霍奇数。这与Schreieder最近的工作有关,但这里的结构更简单。这也包含了一些关于二维几何Hodge结构的推测。

英文摘要:

Call a pure Hodge structure geometric if it is contained in the cohomology of a smooth complex projective variety. The main goal is to show that for any set of Hodge numbers (subject to the obvious constraints), there exists a geometric Hodge structure with precisely these Hodge numbers. This is related to recent work of Schreieder, but the construction here is simpler. This also contains some speculations about 2 dimensional geometric Hodge structures.
