关于曲面上点Hilbert概形的动子

代数几何 2007-05-23 v3

摘要

我们在概形范畴的Grothendieck群中确定了曲面上点Hilbert概形的类。作为推论,我们得到了它在动子(motives)的Grothendieck群中的类。我们给出了一些在曲面层模空间上的应用。本文与de Cataldo和Migliorini的math/0005249相关。

备注

15 pages, Latex. The paper is the same as yesterdays revised version. Only these comments are corrected. The first version of the paper contained a wrong proof that the class of a motive in the Grothendieck group of motives determines its Chow groups with rational coefficients. The mistake was pointed out by B. Totaro. We include a proof also due to B. Totaro that the above statement follows from a conjecture of Beilinson and Murre
