Remarks on weak neighborhood spaces

Abstract

We introduce and study the notions of weak w$psi,phi$-continuity, strong w$psi,phi$-continuity, almost w$psi,phi$-continuity, w$psi,phi$-open function,weakly w$psi,phi$-open function and almost w$psi,phi$-open function. In particular, we investigate the relationships among several types of w$psi,phi$-continuous function and w$psi,phi$-open function.
