โ-Realcompactifications and Normal Bases
In a recent paper (see [2]), Orrin Frink introduced a method to provide Hausdorff compactifications for Tychonoff or completely regular T 1 spaces X . His method utilized the notion of a normal base . A normal base โ for the closed sets of a space X is a base โฆ
