WEAKLY $\alpha_{\gamma}$-REGULAR AND WEAKLY $\alpha_{\gamma}$-NORML SPACES

Alias B. Khalaf, Hariwan Zikri Ibrahim


The aim of this paper is to introduce and study two new classes of
spaces, called weakly $\alpha_{\gamma}$-regular and weakly $\alpha_{\gamma}$-normal spaces. Some basic properties of these separation axioms are studied by utilizing $\alpha_{\gamma}$-open and $\alpha_{\gamma}$-closed sets.
