摘要
在正则远域族的基础上定义了L-fuzzy拓扑空间的相对R-F紧性.并用网和覆盖给出了相对R-F紧性的刻画.研究了相对R-F紧性的性质以及相对R-F紧性与R-F紧性的关系,证明了相对R-F紧性的闭遗传性、传递性与L-好的推广性质.给出了相对R-F紧性的等价刻画.
The definition of relative R-F compactness in L-fuzzy topological space is introduced and characterized in terms of nets and regular open cover. The properties of relative R-F compactness and some connections between the relative R-F compactness and R-F compactness are investigated, and some characteristic theorems of relative R-F compactness are given. It is proved that the L-good extension and heredity about closed subspace are all right.
