论文摘要
我们从Cuntz-Quillen的角度讨论了交叉产品代数的循环同源性。交叉产品代数$ a \ rtimes g $的定期循环同源性是用$ g $的环状亚组的$ g $ a $ g $ action $ g $ action的。
We discuss the cyclic homology of crossed product algebras from the Cuntz-Quillen point of view. The periodic cyclic homology of a crossed product algebra $A\rtimes G$ is described in terms of the $G$-action on periodic cyclic bicomplexes of crossed products of $A$ by the cyclic subgroups of $G$ .
