A note on some applications of -open sets
The object of this note is to introduce and study topological properties of -derived, -border, -frontier, and -exterior of a set using the concept of -open sets. Moreover, we study some further properties of the well-known notions of -closure and -interior. We also obtain a new decomposition of -continuous functions.
