Topological Spaces F_1And F_2

The aim of This work is to present new types of spaces, which are space and space, based on the definition of new types of open sets, which is the feebly open set. we study there the basic properties and also obtained the effects between space and space and with the known space and with closed and open sets

The goal of this work is to present some new separation axioms based on the concept of defining new types of open sets namely semi-feebly open set.  we  investigate their fundamental features
