LF拓扑空间中的U-收敛性和L-fuzzy U-集
U-Convergence and L-Fuzzy U-Sets in LF Topological Spaces
【摘要】 引进了分子网和模糊滤子的U-收敛性以及L-fuzzyU-集等概念,系统地研究了这些概念的特征及其相互关系,推广了HerringtonLL的结果.证明了L-fuzzyU-集是U-闭遗传的、拓扑不变的等重要性质.
【Abstract】 The concepts of U-convergence of molecular nets and fuzzy filters and of L-fuzzy U-sets in L-fuzzy topological spaces are introduced. Their characteristics and mutual relationships are systematically discussed. The results obtained by L. L. Herrington in (1976) are extended. The important properties that the concept of L-fuzzy U-sets is U-closed hereditary and topological invariant are proved.
