• ON ψg*- OPEN MAPS AND ψg*- HOMEOMORPHISMS IN TOPOLOGICAL SPACES

Abstract

In this paper, we define new class of functions namely ψg* – open maps and we prove some of their basic properties. Also, we introduce a new class of ψg* – homeomorphisms and we prove some of their relationship among other homeomorphisms. Throughout this paper f: (X, τ) → (Y, σ) is a function from a topological space (X, τ) to a topological space (Y, σ).
