摘要
This paper is a continuation of [Erguang YANG. On some generalized countably compact spaces. J. Math. Res. Appl., 2019, 39(5): 540–550] in which characterizations of some generalized countably compact spaces such as quasi-γ spaces, quasi-Nagata spaces, wN-spaces and wM-spaces in terms of real-valued functions were obtained. In this paper, we shall present some other forms of characterizations of the spaces mentioned above.
