The process of changing a topology by some types of
its local discrete expansion preserves
-closeness, -closeness, semi-compactness, semi-, semi-, , and extremely disconnectness.
Via some other forms of such above replacements one can have topologies which satisfy
separation axioms the original topology does not have.
