摘要。本文在等变意义上确定了几个Iwasawa模的拟合理想,其中包括最规范的Iwasawa模。通常不是有限射影维的模块本身与所需的有限射影维辅助模块之间的联系是相当明确的。由此产生的拟合理想看起来像斯蒂克尔伯格的理想,并且与栗原最近的工作密切相关。作为一个应用,我们获得了支持Brumer-Stark猜想的新证据。
Abstract.This paper determines, in an equivariant sense, the Fitting ideals of several Iwasawa modules including the most canonical one. The connection between the modules themselves, which are usually not of finite projective dimension, and the required auxiliary modules of finite projective dimension is made rather explicit. The resulting Fitting ideals look like Stickelberger ideals, and there is a close relation with recent work of Kurihara. As an application we obtain new evidence in favor of the Brumer-Stark conjecture.
