Almost Fuzzy Compactness in L-fuzzy Topological Spaces

In this paper, the notion of almost fuzzy compactness is dened in L-fuzzy topological spaces by means of inequality, where L is a completely distributiveDeMorgan algebra. Its properties are discussed and many characterizations of it arepresented.

Inclusive Regular Separation in L-Fuzzy Topological Spaces

In this paper, we first introduce the concept of the inclusive regular separation in L-fuzzy topological spaces. Then we compare the inclusive regular separation with pointed regular separation and regular separation, and discuss the implicative and non-implicative relations among the above three separations. Finally, we illustrate that the inclusive regular separation is harmonic with the inclusive normal separation and inclusive completely regular separation.

L-模糊拓扑空间的一组新的弱分离公理

在L-模糊拓扑空间中引入准分明集的分明度的概念,在此基础上,定义了一组新的弱分离公理,即WiT3,WiT4(i=1,2,3)分离公理,它们比文[1]中的WT3,WT4分离性还要弱,并且证明了它们在L-模糊拓扑空间满层的条件下彼此等价,最后证明了它们也是一般拓扑学中分离性概念在Lowen意义下的“好的推广”.

L-值随机变量

研究L-值随机变量(其中L是闭集格或分子生成格与格上拓扑学有关)。受到已有文献中研究L-拓扑空间的思想、方法和技巧的启发,定义FLc(Rn)={A∈LRn对每个余素元,α{x∈Rn A(x)≥α}是Rn中的非空紧集}上一个分明拓扑TFLc以及L-子集族上的三种度量。在此基础上定义几种L-值随机变量并讨论了它们的初步性质。

Solutions to two problems of G.J.Wang

The problem as to whether the sub-T0 separation and complete regularity are invariant under homeomorphism is answered negatively.And,the problem of multiplicativity of the complete regularity in general L-fuzzy topological spaces is also answered negatively.
