On \(T_{\ddot{g}}\)-Spaces

Abstract

The aim of this paper is to introduce \(T_{\ddot{g}}\)-spaces, \(_g T_{\ddot{g}}\)-spaces and \(_{\alpha}T_{\ddot{g}}\)-spaces. Moreover, we obtain certain new characterizations for the \(T_{\ddot{g}}\)-spaces, \(_g T_{\ddot{g}}\)-spaces and \(_{\alpha}T_{\ddot{g}}\)-spaces.
