【摘要】:讨论csf可数空间的性质,把csf可数空间刻画为度量空间的映像,同时探讨了伪紧的csf可数空间的第一可数性质,推广了Arhangel’skiˇ?关于度量空间伪开s映像的结果,证明了正则伪紧的仿拓扑群是可度量化的当且仅当它是csf可数的Fr′echet空间.
[Abstract]:This paper discusses the properties of csf countable spaces, characterizes csf countable spaces as mappings of metric spaces, discusses the first countable properties of pseudo-compact csf countable spaces, and generalizes the first countable properties of Arhangel'ski countable spaces. On the results of pseudo-open s-mappings in metric spaces, it is proved that a regular pseudo-compact quasi-topological group is metrizable if and only if it is a csf countable Fr'echet space.
