On Intuitionistic Fuzzy Weakly Generalized Closed Set and its Applications

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 ) .
