Nest generated intersection rings in Tychonoff spaces
Nest generated intersection rings in Tychonoff spaces
Tychonoff spaces were characterized by Frink [4] as Ti-spaces possessing normal bases.The zero-sets of continuous real-valued functions provide the best known normal base, but in general there are many others.They need not consist entirely of zero-sets.Each normal base leads to a Hausdorff compactification (called Wallman because of the construction used).If …
