摘要

对于具有有限型仿射群方案作用的域上的有限型分离方案，构造了到Guillot的等变K -同调的双阶等变连接K -理论映射和Thomason的等变代数K -理论。它具有同伦不变性和局域性等所有标准的基本性质。得到了Brown-Gersten-Quillen谱序列的等变版本，并研究了它的收敛性。

Equivariant connective 𝐾-theory

For separated schemes of finite type over a field with an action of an affine group scheme of finite type, we construct the bi-graded equivariant connective K K -theory mapping to the equivariant K K -homology of Guillot and the equivariant algebraic K K -theory of Thomason. It has all the standard basic properties as the homotopy invariance and localization. We also get the equivariant version of the Brown-Gersten-Quillen spectral sequence and study its convergence.
