Definition

  • A bitopological space (X, τ_1, τ_2) is pairwise regular if τ_i closed set C and each point imgtex.fcgi?%5bres=100%5d%7b%5c%5b%20x%5cnotin%20C%20%5c%5d%7d%25.png there is a τ_i open set U and a τ_j open set V disjoint from U such that imgtex.fcgi?%5bres=100%5d%7b%5c%5b%20x%5cin%20U%20%5cmbox%7b%20and%20%7dC%5csubset%20V%2c%5c%20%5cmbox%7bfor%20%7di%2cj=1%2c2%2c%5c%20i%5cneq%20j%20%5c%5d%7d%25.png .
