Uğur Yiğit, Suat Koç, Ünsal Tekir

AI总结:

该研究为交换环上的非零幺模定义了Golomb拓扑,证明了特定条件下互素陪集族可构成拓扑基,同时探究了该拓扑性质与模的代数性质的关联,并用以刻画几类重要模。

摘要:

本文为交换环$R$上的非零幺模$M$引入了一种新的拓扑,称为$R$-模$M$的Golomb拓扑。设$M$为一个$R$-模,$B_{M}$是由互素陪集$\boldsymbol{\textbraceleft}m+N\boldsymbol{\textbraceright}$构成的集族,其中$m \boldsymbol{\boldsymbol{\text{in}}} M$,$N$是$M$的非零子模且满足$N+Rm=M$。我们证明,若$M$是交不可约乘法模,或是交不可约的有限生成模且其每个极大子模都是强不可约的,则$B_{M}$是$M$上某拓扑的基,记为$\boldsymbol{\tilde{G(M)}}$。特别地,$M-\textbraceleft0\textbraceright$上的子空间拓扑称为$R$-模$M$的Golomb拓扑,记为$G(M)$。我们研究了$G(M)$的拓扑性质与$M$的代数性质之间的关联,还利用Golomb拓扑刻画了单模、Jacobson半单模等几类重要的模。

英文摘要:

In this paper, we associate a new topology to a nonzero unital module $M$ over a commutative $R$, which is called Golomb topology of the $R$-module $M$. Let $M\ $be an\ $R$-module and $B_{M}$ be the family of coprime cosets $\{m+N\}$ where $m\in M$ and $N\ $is a nonzero submodule of $M\ $such that $N+Rm=M$. We prove that if $M\ $is a meet irreducible multiplication module or $M\ $is a meet irreducible finitely generated module in which every maximal submodule is strongly irreducible, then $B_{M}\ $is the basis for a topology on $M\ $which is denoted by $\widetilde{G(M)}.$ In particular, the subspace topology on $M-\{0\}$ is called the Golomb topology of the $R$-module $M\ $and denoted by $G(M)$. We investigate the relations between topological properties of $G(M)\ $and algebraic properties of $M.\ $In particular, we characterize some important classes of modules such as simple modules, Jacobson semisimple modules in terms of Golomb topology.
