Lower separation axioms in bifuzzy topological spaces (Q2706965)

The author introduces some weaker forms of pairwise separation axioms viz. \(P\)-\(R_i\), \(P\)-\(R_{i\omega}\), \(P\)-\(T_i\) and \(P\)-\(T_{i\omega}\) \((i=0, 1)\) in a bifuzzy topological space, as generalizations of the existing corresponding axioms in a fuzzy topological space. Basically, it is shown that these separation properties are `good extensions' in the sense defined by the author. There are some examples in the paper, but the proofs are rather straightforward.
