高等等变K-理论的完备化

Completions of Higher Equivariant K-theory

Amalendu Krishna

摘要:

本文的目的是证明一个光滑簇$X$的有理等变K-理论在线性代数群$G$作用下的非阿贝尔局部化定理.然后,我们用这个证明了黎曼-罗克定理,它代表了完成的高等等变K-理论的$X$在各种极大理想的代表环,在等变高等周群。这将Edidin和Graham的一个结果推广到具有有理系数的高阶$K$理论。

英文摘要:

The goal of this paper is to prove a version of the non-abelian localization theorem for the rational equivariant K-theory of a smooth variety $X$ with the action of a linear algebraic group $G$. We then use this to prove a Riemann-Roch theorem which represents the completion of the higher equivariant K-theory of $X$ at various maximal ideals of the representation ring, in terms the equivariant higher Chow groups. This generalizes a result of Edidin and Graham to higher $K$-theory with rational coefficients.
