CM-场等变Iwasawa理论的高余维行为

Higher codimension behavior in equivariant Iwasawa theory for CM-fields

Takenori Kataoka

摘要:

在经典的Iwasawa理论中,我们主要研究算术模的余维1行为。最近,F。M. Bleher,T.钦堡河Greenberg,M. Kakde,G.帕帕斯河Sharifi和M.泰勒开始研究非分歧岩泽模的高余维行为,这些模被证明是伪零的。本文通过发展完备复形的一般代数理论,对他们的工作给出了一个新的视角。这使我们能够将结果扩展到等变设置,即使在非等变设置中,也可以获得有关更高余维行为的更精确的结果。

英文摘要:

In classical Iwasawa theory, we mainly study codimension one behavior of arithmetic modules. Relatively recently, F. M. Bleher, T. Chinburg, R. Greenberg, M. Kakde, G. Pappas, R. Sharifi, and M. J. Taylor started studying higher codimension behavior of unramified Iwasawa modules which are conjectured to be pseudo-null. In this paper, by developing a general algebraic theory on perfect complexes, we obtain a new perspective of their work. That allows us to extend the results to equivariant settings and, even in non-equivariant settings, to obtain more refined results concerning the higher codimension behavior.
