On Some Maps Concerning gα-Open Sets Caldas, M.author Jafari S.author Saraf, R.K.authorIn this paper, we consider a new generalization of $\alpha$-open maps via the concept of g$\alpha$-closed sets which we call approximately $\alpha$-open maps. We study some of its fundamental properties. It turns out that we can use this notion to obtain a new characterization of $\alpha-T_\frac{1}{2}$ spaces. 2001 Mathematics Subject Classification: 54805, 54C08 Q Science, Computer Science2007Penerbit Universiti Sains MalaysiaJournal
