摘要
借助相关远域族定义了L-双拓扑空间中可数配超紧集,研究了其基本性质,证明了可数配超紧性是闭遗传性和弱拓扑不变性。
The definition of countably pairwise ultra-compacted set is given by relative R-neighborhood family in L-bitopological space, its properties are studied, and it is proved that the countably pairwise ultra-compactness are hereditary with respect to closed subsets andweakly topological properties.
