T. Noiri, M. B. Ahmad and M. Khan introduced the notion of almost s-continuous functions [20] since then the function studied by various authors [1,4,11] Continuing in the spirit of this papers we obtain several properties and new characterizations of almost s-continuous functions. We improve and strengthen some of the known results. The concept of co-SR-closed graph is introduced.
