Definition
- A topological space (X,τ) with an operation γ on τ is called γ-βT_1 if and only if for each pair of distinct points x, y in X, there exists two γ-β-open sets U and V such that x ∈ U,
and y ∈ V.
Property
- A topological space (X,τ) with an operation γ on τ is γ-βT_1 if and only if every singleton {x} is γ-β-closed.
- γ-βT_1 ⇒ γ-βT_{1/2}.
