摘要
借助于ωβ-闭集,在Lω-空间中定义了ωβ-连通集和ωβ-连通空间的概念.给出了ωβ-连通性的等价刻画,讨论了ωβ-连通性的基本性质,证明了ωβ-连通性是同胚不变性.
In this paper, connectivity called ωβ-connected set and ωβ-connected space in Lβ-spaces is intro- duced by means of ωβ-closed sets. Some equivalent characterizations of ωβ-connectedness are given and some fundamental properties of ωβ-connectedness are discussed. It is proved that ωβ-connectedness is in- variant under order homeomorphism.
