关于曲线与阿贝尔簇乘积的零维 Chow 群的滤波

A Filtration of the Chow Group of Zero-Cycles for a Product of Curves and an Abelian Variety

Thomas Jaklitsch

AI总结:

本文提出了一种针对曲线与阿贝尔簇乘积的零维 Chow 群的滤波方法,并通过 Somekawa K-群描述了其生成元和关系。

摘要:

本文中,我们定义了对于形式为 $A \times C_1 \times \cdots \times C_d$ 的变种的零维 Chow 群的降滤波。我们给出了这种滤波的 successive quotients 的显式生成元和关系,通过证明它们可以由 Somekawa K-群描述。这扩展了 Raskind 和 Spiess 对曲线乘积的研究,以及 Gazaki 对阿贝尔簇的研究。

英文摘要:

In this paper we define a descending filtration on the Chow group of zero cycles for varieties of the form $A \times C_1 \times \cdots \times C_d$ where $A$ is an abelian variety and each $C_i$ is a smooth projective curve. We give explicit generators and relations for the successive quotients of this filtration by showing that they can be described by Somekawa K-groups. This extends the work of Raskind and Spiess who proved this result for products of curves and Gazaki who proved this for abelian varieties.
