The goal of this a book is to recall some types of weak open sets, prove
some of its properties and use them to define new kinds of separation
axioms. Let us state below some of our important main theorems Let (X,σ)
and (Y,τ) be two topological spaces satisfy the ω-condition then the map
f: (X,σ)⟶(Y,τ) is continuous if and only if it is ω-continuous. ( This
result is not true without ω-condition ), also Let (X,σ) and (Y,τ) be
two topological spaces satisfy the ω-B_α-condition then the map f:
(X,σ)⟶(Y,τ) is continuous if and only if it is α-ω-continuous. And Let
(X,σ) and (Y,τ) be two topological spaces satisfy the ω-B-condition then
the map f: (X,σ)⟶(Y,τ) is continuous if and only if it is
pre-ω-continuous. Addition Let (X,σ) and (Y,τ) be two door topological
spaces and f: (X,σ)⟶(Y,τ) be a map, then f is pre-ω-continuous if and
only if it is ω-continuous. And f is β-ω-continuous if and only if it is
b-ω-continu
