摘要：
New classes of sets called Omega-closed sets and Omega s-closed sets are introduced and studied. Also, we introduce and study Omega-continuous functions and Omega s-continuous functions and prove pasting lemma for these functions. Moreover, we introduce classes of topological spaces called Omega - T1/2 and Omega - T-s.
