Minimal and Maximal Feebly Open Sets

In this paper we introduced many new concepts all of these concepts completely depended on the concept of feebly open set. The main concepts which introduced in this paper are minimal f-open and maximal f-open sets. Also new types of topological spaces introduced which called Tf min and Tf max spaces. Besides, we present a package of maps called: minimal f-continuous, maximal f-continuous, f-irresolute minimal, f-irresolute maximal, minimal f-irresolute and maximal firresolute. Additionally we investigated some fundamental properties of the concepts which presented in this paper.
