Abstract
Kandil, Kerre and Nouh unifed some concepts in fuzzy topological spaces
by using operations. By adapting the defnition of an operation and some
defnitions given by these authors to topological spaces, and by giving some
new defnitions, we have achieved some unifcations related to compactness,
continuity, openness and closedness of functions. Here, we will study unifications related to separation axioms, such as $T_i (i = 0, 1, 2)$ and $R_2$.
