• On 𝛂g𝛅-regular and 𝛂g𝛅- normal spaces

Abstract

We introduce a new types of separation axioms say - spaces, for i = 1/2, b and we study some of their properties. We define also the class of -regular and -normal spaces and show that -regularity and -normality are preserve under bijective continuous and pre- -open mappings. Several properties of these spaces are discussed.
