On Weak Separation Axioms via (1, 2)*-Semi-Generalized Closed Sets

The aim of this paper is to introduce and study two new classes of bitopological spaces called (1,2)*-semi-g-regular and (1,2)*-semi-g- normal spaces. (1,2)*-semi-g-regularity and (1,2)*-semi-g-normality are separation properties obtained by utilizing (1,2)*-semi-generalized closed sets.
