摘要翻译:
我们通过对应证明了代数群SL(2)作用于任意极化阿贝尔簇A。结果,我们恢复了SL(2)对Chow群CH(a)(有理系数)的作用,从而得到了a上代数圈的Lefschetz型性质。

英文摘要:
We show that the algebraic group SL(2) acts on any polarized abelian variety A through correspondences. As a consequence we recover the action of SL(2) on the Chow group CH(A) (with rational coefficients), and this gives rise to Lefschetz type properties for algebraic cycles on A .
