“…A set A of X is called (i) supra semi-open set (Levine, 1991) (Devi et al, 2008), if A ⊆ int µ (cl µ (int µ (A))). (iii) supra Ω closed set (Noiri and Sayed, 2005), if scl µ (A) ⊆ int µ (U ), whenever A ⊆ U , U is supra open set. (iv) supra N-closed set (Vidyarani and Vigneshwaran, 2013a), if Ωcl µ (A) ⊆ U , whenever A ⊆ U, U is supra α open set.…”
