Abstract:
We provide some conditions as to when for two locally compact spaces and (where is the lattice of all Hausdorff compactifications of ). More specifically, we prove that if and only if . Using this result, we prove several extensions to the case where is embedded as a sub-lattice of and to where and are not locally compact.
One major contribution is in the use of function algebra techniques. The use of these techniques makes the extensions simple and clean and brings new tools to the subject.
