| Abstract: | In this paper we introduce and investigate the notions of a new class of generalized semi-closed functions and a class of semi-generalized closed functions in bitopological spaces. We study the further properties of ij-generalized semi closed and ij-semi-generalized closed sets. Applying of these concepts of sets, we introduce and study two new spaces, namely pairwise generalized s-regular and pairwise s-normal spaces. |
