摘要
The object of this note is to introduce and study topological properties of %26#945;-derived, %26#945;-border, %26#945;-frontier, and %26#945;-exterior of a set using the concept of %26#945;-open sets. Moreover, we study some further properties of the well-known notions of %26#945;-closure and %26#945;-interior. We also obtain a new decomposition of %26#945;-continuous functions.
