GENERALIZED δ- SEMICLOSED SETS IN BITOPOLOGICAL SPACES

Document Type : Novel Research Articles

Abstract

In this paper we introduce and study ij -gδ s -closed sets and study some of its
properties and its relations with other kinds of generalized closed sets in bitopological
spaces. Using these sets we obtain a characterization of pairwise 34
T spaces. Also we introduce the concepts of pairwise gδs- continuous and pairwise gδs- irresolute
functions. Finally we define the concept of pairwise gδsc-homeomorphism and prove that the set of all pairwise gδsc- homeomorphisms from (X ,τ12) onto itself has a group structure under the composition.
