Definition

  • A topological space (X,τ) with an operation γ on τ is called γ-βT_0 if and only if for each pair of distinct points x, y in X, there exists an γ-β-open set U such that either x ∈ U and imgtex.fcgi?%5bres=100%5d%7b%5c%5b%20y%5cnotin%20U%5cmbox%7b%20or%20%7dx%5cnotin%20U%20%5c%5d%7d%25.png and y ∈ U.
