Functions Near Of Na-Continuity By

Abstract

In 1986, the concept of Na-continuity was initiated by Chae et al., this leads us to introduce two classes of functions, namely strongly Na-continuity and weakly Na-continuity. We characterize these new types. Several properties of them are studied. Also, their relationship with other types of functions are investigated. Finally, the effects of these functions on some topological spaces are established.
