On Intuitionistic Fuzzy Generalized b Closed Sets

(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, the notation A =  x, μA, νA  shall be used 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) .
