摘要
In this paper, we give the mapping theorems on \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$\aleph$$ \end{document}-spaces and g-metrizable spaces by means of some sequence-covering mappings, mssc-mappings and π-mappings.
