Remarks on weakly star countable spacesYK. Song and WF. XuanSchool of Statistics and Mathematics, Nanjing Audit University, Nanjing 210093, P.R. China Email: wfxuan@nau.edu.cnAbstract: A space $X$ is {\it weakly star countable} if for each open cover $U$ of $X$ there exists a countable subset $F$ of $X$ such that $\overline{\bigcup_{x\in F}St(x, U)}=X$. In this paper, we investigate topological properties of weakly star countable spaces. Keywords: Star countable; weakly star countable.
