L—Fuzzy拓扑空间的仿紧性和强仿紧性

仿紧性是分明拓扑学中的一个重要概念,如何合理定义LF拓扑中的仿紧性是一引人注目的课题。基于良紧性的几何刻划[4],文[3]和文[2]分别引入F拓扑中的局部有限族和仿紧性。文[2]对弱诱导的仿紧空间进行了比较深入的研究。但[2]和[3]的讨论还没有涉及到仿紧性的可乘性、分离性等问题。此外[2]引入了另一种局部有限性质:

文（１）曾在广义拓扑分子格中提出了一种连通性。本文在Ｌ－ｆｕｚｚｙ拓扑空间中给出了这种连通性的几种刻划，并引入了Ｌ－ｆｕｚｚｙ拓扑空间的局部连通性，这种局部连通性是有限可乘的，商序同态保持的且是好的推广，另外，ｆｕｚｚｙ实直线是局部连通的。     

基数函数对L—Fuzzy拓扑空间中某些拓扑性质的刻划

基数函数的研究是集论拓扑当中的一个重要分支。它可以定量地刻划一些拓扑性质之间的关系,像大家熟知的具有可数基的拓扑空间有可数的稠子集这一性质,是一个很好的例子。文[1]建立了L-Fuzzy拓扑空间的系统理论,由于多了一个层次结构,这种理论有不少创新并且是富于更多的技巧的。不过在这一框架之下,利用基数函数探讨L-Fuzzy拓扑学中的拓扑性质,尚未深入展开。本文中,利用L-Fuzzy拓扑空间中的一些基数函数,结合格L的层次结构特点, 给出了良紧空间与诱导空间中若干进一步

L-fuzzy拓扑空间中的相对良紧性

The concept of relative N-compactness is defined and characterized in terms of nets. It is shown that the relative N-compactness is hereditary with respect to L-fuzzy sets and the relative N-compactness is L-good extension. Some connections between the N- compactness and the relative N-compactness are investigated. It is also proved that induced relative N-compact spaces are productive, and the product of finite relative compact sets is relative compact.     

Fuzzy Perfect Mappings and Q-Compactness in Smooth Fuzzy Topological Spaces

We point out that the product of two fuzzy closed sets of smooth fuzzy topological spaces need not be fuzzy closed with respect to the the existing notion of product smooth fuzzy topology. To get this property, we introduce a new suitable product smooth fuzzy topology. We investigate whether $F_1\times F_2$ and $(F,H)$ are weakly smooth fuzzy continuity whenever $F_1$, $F_2$, $F$ and $H$ are weakly smooth fuzzy continuous. Using this new product smooth fuzzy topology, we define smooth fuzzy perfect mapping and prove that composition of two smooth fuzzy perfect mappings is smooth fuzzy perfect under some additional conditions. We also introduce two new notions of compactness called $Q$-compactness and $Q$-$\alpha$-compactness; and discuss the compactness of the image of a $Q$-compact set ($Q$-$\alpha$-compact set) under a weakly smooth fuzzy continuous function ($(\alpha ,\beta )$-weakly smooth fuzzy continuous function).

Homomorphic images and preimages are also examined. Finally, some definitions and results on fuzzy soft set are studied.

Fuzzy Closure Spaces vs. Fuzzy Rough Sets

This paper investigates the relationship among fuzzy rough sets, fuzzy closure spaces and fuzzy topology. It is shown that there exists a bijective correspondence between the set of all fuzzy reflexive approximation spaces and the set of all quasi-discrete fuzzy closure spaces satisfying a certain extra condition. Similar correspondence is also obtained between the set of all fuzzy tolerance approximation spaces and the set of all symmetric quasi-discrete fuzzy closure spaces satisfying a certain extra condition.
