在LF-拓扑空间中,文[2,3]引进了强F1连通的概念,并研究了其基本性质.本文利用层次闭集和层次开集给出了强F1连通的若干新特征.
In LF-topological spaces,Li [2] and Lu[3] investigated a notion of strong F2 connectedness and studied its basical properties.In this paper,we present some new characterizations of strong F2 connectedness by some kinds of layer closed sets and layer open sets.
