ON S – Normal Space and Some Functions

Abstract

The notion of S-normal Space was introdneed by S.N.Maheshwari and R. Prasad (3) by replacing open set in the definition of normal space by semi-open set fhriefty x open sets due to levine (1). The Purpose of this work is to find more characterization of S- normal Space by using New class of sets called Generalized Semi Open Set ( brielly gs-open set) Where we shall introduce new definition equivalent to the definition of S-normal space by using ( gs-open set ) instead of ( S-open set ) also we introduce some preseration theorems conceming S-normal space by using New class of funetions as pre gs-closed and pre gs-contious funetion.
