On the -Equivalence of Generalized Ordered Sets

On the -Equivalence of Generalized Ordered Sets

We consider the generalized ordered spaces  and  such that the tightness  coincides with the tightness  but and have different cardinalities. Some sufficient conditions are found under which such spaces  and  are not -equivalent.
