为改进Fuzzy HX环的结果,使之包含Fuzzy商环,提出了弱Fuzzy HX环的概念,研究了它的性质与结构,并重新讨论了拟Fuzzy商环,证明了在正则条件下拟Fuzzy商环与弱Fuzzy HX环的统一性:同时也得到了一致弱Fuzzy HX环与普通Fuzzy商环的关系。 相似文献

文[1]首次提出了HX环(幂环)的概念,文[2]探索了幂环的性质和结构,本文类似于幂群的研究,提出了正规幂环和一致幂环的概念,研究了它们的结构和它们之间的关系,对它们进行了分类,并讨论了它们的交与和,从而构造了它们的子环链和理想链。 相似文献

一类环上HX环的结构 总被引:11,自引:2,他引:9
自李洪兴1991年提出了HX环以来,人们一直有这么一个问题没解决,就是是否存在非平凡的HX环的例子?但至今既没找到非平凡的HX环,也没有证明任一环R仅存在平凡的HX环。针对这个问题,本文提出并证明了一类环仅有平凡HX环,还给出了一系列的结构定理。这样,既为证明任一环R仅有平凡的HX环的猜想有新的启示,也为人们指明无须在这一类环上寻找非平凡HX环。 相似文献

Let R be a ring and define x ○ y = x + y - xy, which yields a monoid (R, ○), called the circle semigroup of R. This paper investigates the relationship between the ring and its circle semigroup. Of particular interest are the cases
where the semigroup is simple, 0-simple, cancellative, 0-cancellative, regular, inverse, or the union of groups, or where
the ring is simple, regular, or a domain. The idempotents in R coincide with the idempotents in (R, ○) and play an important role in the theory developed.

In this paper the idea of an intrinsic extension of a ring, first proposed by Faith and Utumi, is generalized and studied in its own right. For these types of ring extensions, it is shown that, with relatively mild conditions on the base ring, R, a complete set of primitive idempotents (a complete set of left triangulating idempotents, a complete set of centrally primitive idempotents) can be constructed for an intrinsic extension, T, from a corresponding set in the base ring R. Examples and applications are given for rings that occur in functional analysis and group ring theory. 相似文献

In order to construct nonregular power rings, the concept of regular semi-ideal with respect to a subring is introduced. Then
several constructive theorems of HX ring and power ring are established and some examples of non-regular power rings are constructed
which contain some nonregular HX rings. 相似文献
