On some properties of generalized open sets in generalized topological spaces

In [8], Császár introduced some generalized open sets in generalized topological spaces, namely, μ -semi-open, μ -preopen, μ-β -open, and μ-α -open. The primary purpose of this paper is to study some new properties and characterizations of these concepts as we also introduce and study a new generalized open set in generalized topological spaces, namely, μ-b -open. We also investigate some relationships between these concepts.
