交换环上模的PS-Hollow表示

PS-Hollow Representations of Modules over Commutative Rings

Jawad Abuhlail, Hamza Hroub

摘要:

设$R$是交换环,$M$是非零$R$ -模.引入了$M$的类\emph{pseudo strongly hollow submodules}(简称\emph{PS-hollow submodules}).受具有\emph{secondary representations}的模理论的启发,我们研究了可表示为PS-中空子模的\emph{finite}和的模.特别地,我们给出了Artin环上模的\emph{minimal} PS-空强表示的存在性和唯一性定理.

英文摘要:

Let $R$ be a commutative ring and $M$ a non-zero $R$-module. We introduce the class of \emph{pseudo strongly hollow submodules} (\emph{PS-hollow submodules}, for short) of $M$. Inspired by the theory of modules with \emph{secondary representations}, we investigate modules which can be written as \emph{finite} sums of PS-hollow submodules. In particular, we provide existence and uniqueness theorems for the existence of \emph{minimal} PS-hollow strongly representations of modules over Artinian rings.
