More on Arhangel'skiĭ sheaf amalgamations


Meiyan Liu, Jiakui Yu, Shuguo Zhang




We proceed to consider the topic of ideal-convergence. In particular, we introduce the ideal-version of Arhangel'skiĭ sheaf amalgamations, and exam the relations among the ideal-version of Arhangel'skiĭ sheaf amalgamations, ideal-version of QN-spaces and ideal-version of covering properties. Some characterizations of ideal-version of Arhangel'skiĭ sheaf amalgamations will be given. Our observations extend some classic results.
