对应与奇异簇

Correspondences and singular varieties

Robert Laterveer

摘要:

通常被称为“布洛赫-斯里尼瓦什方法”的是分解光滑射影簇的对角线,然后考虑上同调中对应的作用。在本文中,我们观察到同样的方法也可以推广到奇异和拟射影簇。我们给出了两个应用程序的这一观察:第一个是一个版本的芒福德定理,第二个是有关霍奇猜想的奇异品种。

英文摘要:

What is generally known as the "Bloch--Srinivas method" consists of decomposing the diagonal of a smooth projective variety, and then considering the action of correspondences in cohomology. In this note, we observe that this same method can also be extended to singular and quasi--projective varieties. We give two applications of this observation: the first is a version of Mumford's theorem, the second is concerned with the Hodge conjecture for singular varieties.
