本文通过一个序半群S上的一些二元关系以及它的理想的根集的性质该序半群是阿基米德半群的半格,特别地是阿基米德半群的链的刻划,证明了S是阿基米德链当且仅当S是准素的.通过序半群的m-系的概念,证明了S的任意半素理想是含它的所有素理想的交,并通过该结论,证明了S是阿基米德半群的链当且仅当S是阿基米德半群的半格且S的所有素理想关于集包含关系构成链.作为应用,该结论在一般的半群(没有序)[1]中也成立. 相似文献

在序半群上定义了几种新的关系,利用它们得到了序半群上最小完全半素理想的结构,并以此给出了序半群的最小正则半格同余的另一种描述,所得结果是Miroslav Ciric在文[1]中的部分结果向序半群上的推广。 相似文献

本文通过一个序半群S上的一些二元关系以及它的理想(右理想,双理想)的根集分别给出了该序半群是阿基米德(右阿基米德,t-阿基米德)序子半群的链的刻画.进一步证明了准素序半群是阿基米德序半群的链.最后,通过素根定理证明了序半群S是阿基米德序子半群的链当且仅当S是阿基米德序子半群的半格且S的所有素理想关于集合的包含关系构成链. 相似文献

For a monoid M, we introduce the concept of skew strongly M-reversible rings which is a generalization of strongly M-reversible rings, and investigate their properties. It is shown that if G is a finitely generated Abelian group, then G is torsion-free if and only if there exists a ring R with |R| ≥ 2 such that R is skew strongly G-reversible. Moreover, we prove that if R is a right Ore ring with classical right quotient ring Q, then R is skew strongly M-reversible if and only if Q is skew strongly M-reversible. 相似文献

In this paper, the concept of quasi-prime fuzzy left ideals of an ordered
semigroup $S$ is introduced. Some characterizations of strongly semisimple ordered
semigroups are given by quasi-prime fuzzy left ideals of $S$. In particular, we prove
that $S$ is strongly semisimple if and only if each fuzzy left ideal of $S$ is the intersection
of all quasi-prime fuzzy left ideals of $S$ containing it. 相似文献

Let S be an ordered semigroup.In this paper,we characterize ordered semigroups in which the radical of every ideal(right ideal,bi-ideal) is an ordered subsemigroup(resp.,ideal,right ideal,left ideal,bi-ideal,interior ideal) by using some binary relations on S. 相似文献

In this paper,fuzzy quasi-ideals of ordered semigroups are characterized by the properties of their level subsets.Furthermore,we introduce the notion of completely semiprime fuzzy quasi-ideals of ordered semigroups and characterize strongly regular ordered semigroups in terms of completely semiprime fuzzy quasi-ideals.Finally,we investigate the characterizations and decompositions of left and right simple ordered semigroups by means of fuzzy quasi-ideals. 相似文献

我们通过本原逆半群作用在强〈E〉-酉,〈E〉-稠密范畴上,给出了0-范畴,(强)〈E〉*-稠密,强〈E〉*-酉半群的一个刻画.我们也证明了每一个0-范畴,强〈E〉*-稠密半群有一个0-范畴,(强)〈E〉*-稠密,强〈E〉*-酉的覆盖. 相似文献

A proper ideal M of an ordered semigroup (S, ·, ≤) is said to be a covered ideal of S if M ? (S(S?M)S], i.e., if for any x in M, there exist a, c in S and b in S?M such that x ≤ abc. The purpose of this article is to study the structure of ordered semigroups containing covered ideals. The results obtained generalize the results on semigroups (without order) studied by Fabrici in 1984. 相似文献

设S是有向序半群,本文给出了S上的一类正则同余,称为强序同余的定义及性质.证明了S的强序同余是强正则同余,但反之不成立.同时证明了强序同余格SOC(S)是S的同余格C(S)关于通常集合的交和传递积的V-完备的分配子格. 相似文献
