关于等变高阶Chow群的注记

Notes on equivariant higher Chow groups

Nguyen Manh Toan

摘要:

本文证明了具有有限群作用的代数簇的Levine-Serpé等变高阶Chow群与具有不动点的普通高阶Chow群的一个比较定理。结果表明,等变动机谱序列是理性退化的。这产生了等变代数$K$ -理论的Riemann-Roch定理。

英文摘要:

In this short note, we prove a comparision theorem between Levine-Serpé's equivariant higher Chow groups of an algebraic variety equipped with an action of a finite group and ordinary higher Chow groups of its fixed points. As a consequence, we show that the equivariant motivic spectral sequence degenerates rationally. This yields a Riemann-Roch Theorem for equivariant algebraic $K$-theory.
