Quasi B-Normal Spaces

Characterizations and preservation theorems of quasi b-normal spaces

Abstract

– In this paper, we introduced theconcept of quasi b-normal spaces in topological spaces by using b-open sets dueto Andrijevic [1] and obtained several properties of such space. We introducedthe concepts of gb-closed, pgb-closed, almostb-closed, almost gb-closed, almost pgb- closed, pgb-continuous and almost pgb-continuous functions. Moreover, we obtain some newcharacterizations and preservation theorems of quasi b-normal   spaces.
