SPG-Separation Axioms

In this paper by using spg-open sets we define almost spg-normality and mild spg-normality also we continue the study of further properties of spg-normality. We show that these three axioms are regular open hereditary. We also define the class of almost spg-irresolute mappings and show that spg-normality is invariant under almost spg-irresolute M-spg-open continuous surjection.
