Objectives: The separation axioms are about the use of kasaj topological means to distinguish disjoint sets and distinct points and the purpose of this work is to investigate the spaces namely KSgp[KSgsp]-T 0 spaces, KSgp[KSgsp]-T 1 spaces, KSgp[KSgsp]-T 2 spaces by utilizing KSgp[KSgsp]-open sets in Kasaj topological spaces. Also, we discuss their relationship with existing concepts in Kasaj topological spaces. Methods: Any two Kasaj topologically distinguishable points must be distinct, and any two separated points must be Kasaj topologically distinguishable. Finding: This study consists of three separation axioms namely KS gp [KS gsp ]-T 0 spaces, KS gp [KS gsp ]-T 1 spaces, KS gp [KS gsp ]-T 2 spaces by utilizing KS gp [KS gsp ]-open sets in Kasaj topological spaces. Novelty: This study uses their relationship with existing concepts in Kasaj topological spaces.
