Stiefel簇的动机上同调

The Motivic Cohomology of Stiefel Varieties

Ben Williams

摘要:

本文的主要结果是计算了n个秩为m的\times m-矩阵簇的动机上同调,包括环的结构和约化幂运算的作用.论证通过比较一般线性群-方案与具有不相交基点的射影n - 1-空间的A1-等价空间的Tate悬挂来进行。

英文摘要:

The main result of this paper is a computation of the motivic cohomology of varieties of n \times m-matrices of of rank m, including both the ring structure and the action of the reduced power operations. The argument proceeds by a comparison of the general linear group-scheme with a Tate suspension of a space which is A1-equivalent to projective n - 1-space with a disjoint basepoint.
