Iwasawa模理论的主要结论是预测了Iwasawa模与$p$-adic $L$-函数之间的关系。Greither和Kurihara利用主猜想的一个已证明的公式,明确地描述了全真实的域的有限交换扩张的分圆$\mathbb{Z}_p$-扩张的岩泽模的(初始)Fitting理想.在本文中,我们推广了代数理论背后的工作,通过发展理论的拟合不变量的``移位。作为对岩泽理论的应用,我们得到了Greither和Kurihara工作的一个非对易版本和一个双变量版本。
The main conjectures in Iwasawa theory predict the relationship between the Iwasawa modules and the $p$-adic $L$-functions. Using a certain proved formulation of the main conjecture, Greither and Kurihara described explicitly the (initial) Fitting ideals of the Iwasawa modules for the cyclotomic $\mathbb{Z}_p$-extensions of finite abelian extensions of totally real fields. In this paper, we generalize the algebraic theory behind their work by developing the theory of ``shifts of Fitting invariants.'' As applications to Iwasawa theory, we obtain a noncommutative version and a two-variable version of the work of Greither and Kurihara.
