模糊半开集和半分离性公理 总被引:5,自引:0,他引:5
本文改进了文[3]的模糊半开集定义,在本文定义的模糊半开集定义,不仅可以完全保留文[3]的结论,而且还能建立分明拓扑空间及其诱导拓扑空间关于半开集、半闭集等对应关系。此外,本文借助重域概念重新定义了半-R0,半-R1和半-T2空间,与[4]相比,本文定义的半分离性公理体系可以更自然地推广分明拓扑空间中的有关定理。 相似文献

This paper provides a new connection between algebraic hyperstructures and fuzzy sets. More specifically, using both properties of fuzzy topological spaces and those of fuzzy subhypergroups, we define the notions of lower (upper) fuzzy topological subhypergroups of a hypergroup endowed with a fuzzy topology. Some results concerning the image and the inverse image of a lower (upper) topological subhypergroup under a very good homomorphism of hypergroups (endowed with fuzzy topologies) are pointed out. 相似文献

In this paper, the concretely both reflective and coreflective subconstructs of the construct CFTS of Chang fuzzy topological spaces are characterized and their relationship to such subconstructs of stratified fuzzy topological spaces is investigated. Properties of a particular such subconstruct of CFTS, the construct of weak fuzzy neighborhood spaces, are discussed in detail. And it is proved that there exists exactly c such subconstructs between the subconstruct of weakly induced spaces and CFTS. 相似文献

The goal of this paper is to compare certain topological and uniform structures on sets of fuzzy numbers. Since fuzzy sets can be viewed as a kind of subsets they can be endowed with uniform structures in ways similar to those used for classic subsets. The Hausdorff construction is one such approach. The structures we study are the myope structure, the uniform convergence of the cuts in the sense of Hausdorff, and a structure induced by a metric defined by Goetschel and Voxman. We show how these structures are related to fixed point problems for some classes of fuzzy numbers. 相似文献
