K3曲面的Chow环

The Chow ring of a K3 surface

Arnaud Beauville, Claire Voisin

摘要:

设X为K3曲面。本文证明了0-圈的Chow群CH_0(X)包含一个1次的“基本类”c_X,它具有以下显著的性质:任何因子的乘积都与这个类成正比,第二类c_2(X)也是如此。本预印本取代了第一作者的预印本math.AG/0109063,后者的性质被证明。

英文摘要:

Let X be a K3 surface. We show that the Chow group CH_0(X) of 0-cycles contains a "fundamental class" c_X of degree 1 with remarkable properties: any product of divisors is proportional to this class, and so is the second Chern class c_2(X). This preprint supersedes the preprint math.AG/0109063 by the first author, where the latter property was conjectured.
