代数群E_6、E_7和E_8的Chow环

The Chow rings of the algebraic groups E_6, E_7, and E_8

Shizuo Kaji, Masaki Nakagawa

摘要:

确定了例外型E_6、E_7和E_8的复代数群的Chow环,给出了由相应旗簇的Schubert簇的拉回像表示的显式生成元.这是R. Marlin关于SO_n,Spin_n,G_2和F_4的Chow环的计算.我们的方法是基于Schubert演算的相应的旗品种,这有自己的利益。

英文摘要:

We determine the Chow rings of the complex algebraic groups of the exceptional type E_6, E_7, and E_8, giving the explicit generators represented by the pull-back images of Schubert varieties of the corresponding flag varieties. This is a continuation of the work of R. Marlin on the computation of the Chow rings of SO_n, Spin_n, G_2, and F_4. Our method is based on Schubert calculus of the corresponding flag varieties, which has its own interest.
