Regular Weakly Generalized Closed Sets in Intuitionistic Fuzzy Topological Spaces

B = { x, μB(x), νB(x)  / x  X}. Then (a) A  B if and only if μA(x) ≤ μB (x) and νA(x) ≥ νB(x) for all x  X (b) A = B if and only if A  B and B  A (c) A c = { x, νA(x), μA(x)  / x  X} (d) A  B = { x, μA(x)  μB(x), νA(x)  νB(x)  / x  X} (e) A  B = { x, μA(x)  μB(x), νA(x)  νB(x)  / x  X} For the sake of simplicity, we shall use the notation A =  x, μA, νA  instead of A = { x, μA(x), νA(x)  / x  X}. Also for the sake of simplicity, we shall use the notation A =  x, (μA, μB ), (νA, νB)  instead of A =  x, (A/μA, B/μB), (A/νA, B/νB) .
