摘要
本文在L—fts中引入了强远域族与局部强远域族性质两个概念,并探讨了这两个概念自身的某些性质及与强Q紧、良紧之间的关系。
In this paper we introduce the notions of the strong remote neiborhood family property and the locally strong remote neiborhood family property.We discuss some properties of the two notions and give some relations between the two notions and N-compactness. We obtain a new characterization. of N-compactness in fts: fts (X, J) is N-compact iff it is strong Q-compact and has the locally strong remote neiborhood family property.
