拓扑K理论的代数K理论的局部化序列
The localization sequence for the algebraic K-theory of topological K-theory
摘要:
通过建立拓扑K理论的代数K理论的一个局部化共纤谱序列K(Z)到K(ku)到K(KU)到Sigma K(Z),证明了Rognes的一个猜想.我们推导出这个序列的存在性作为一个devissage定理的结果,该定理将连通A-无限环谱R上模的Postnikov塔的Waldhausen范畴的K-理论与π-生成的pi_0(R)-模的阿贝尔范畴的Quillen K-理论相鉴别。
英文摘要:
We prove a conjecture of Rognes by establishing a localization cofiber sequence of spectra, K(Z) to K(ku) to K(KU) to Sigma K(Z), for the algebraic K-theory of topological K-theory. We deduce the existence of this sequence as a consequence of a devissage theorem identifying the K-theory of the Waldhausen category of Postnikov towers of modules over a connective A-infinity ring spectrum R with the Quillen K-theory of the abelian category of finitely generated pi_0(R)-modules.
