一类代数超Kähler流形的Chow环

On the Chow ring of certain algebraic hyper-Kähler manifolds

C. Voisin

摘要:

研究了Beauville关于超Kähler代数簇的Chow环的一个猜想的推广.也就是说,我们证明了在许多情况下,仅涉及CH ^1(X)和X的陈类的多项式上同调关系在CH(X)中满足。这些案例是:K3曲面S参数化长度为n的子格式的点Hilbert格式,其中n<2b_2(S)_tr+5;

英文摘要:

We study a generalization of a conjecture made by Beauville on the Chow ring of hyper-Kähler algebraic varieties. Namely we prove in a number of cases that polynomial cohomological relations involving only CH^1(X) and the Chern classes of X are satisfied in CH(X). These cases are : punctual Hilbert schemes of a K3 surface S parameterizing subschemes of length n, for n<2b_2(S)_tr+5; Fano varieties of lines in a cubic fourfold.
