Abstract :
The aim of this paper is to introduce and study two new classes of functions called weakly open functions and weakly closed functions via the concept of e∗-open set defined by Ekici cite{erd1}. The notions of weakly open and weakly closed functions are weaker than the notions of weakly open and weakly β-closed functions defined by Caldas and Navalagi cite{cal}, respectively. Moreover, we investigate not only some of their fundamental properties, but also their relationships with other types of existing topological functions.
