利用环面作用的等变上同调的Berline-Vergne积分公式,证明了重言丛特征类的Grassmannian(经典的、Lagrange的或正交的)上的积分可以表示为某些多元全纯函数在无穷远处的迭代留数.这些情况下得到的结果可以表示为一个公式的特殊情况下,涉及外尔群的作用的性质的自然表示的环面。
Using the Berline-Vergne integration formula for equivariant cohomology for torus actions, we prove that integrals over Grassmannians (classical, Lagrangian or orthogonal ones) of characteristic classes of the tautological bundle can be expressed as iterated residues at infinity of some holomorphic functions of several variables. The results obtained for these cases can be expressed as special cases of one formula involving the Weyl group action on the characters of the natural representation of the torus.
