诺特环R的理想I的约化的概念以及I在R中的积分闭包I* 和R的元素x对I的积分依赖的相关概念在交换代数中的许多情况下都被证明是有用的。本文的目的是将这些概念扩展到模块。为了激发下面的定义,在把理想推广到模之前考虑这些概念是有用的。
The notion of a reduction of an ideal I of a noetherian ring R and the related notions of the integral closure I* of I in R and the integral dependence of an element x of R on I have proved useful in many situations in commutative algebra. The purpose of this paper is to extend these notions to modules. To motivate the definitions which follow, it will be useful to consider these notions for ideals before extending them to modules.
