We said that G [??] X is a residual set, if there is a family of open sets ([U.sub.n])n[member of][??] which are dense in X such that [intersection]n[member of][??] [U.sub.n] [??] G.
Then we conclude that [R.sub.n] is a residual set in [A.sub.n] for each n [member of] N.
We say [F.sub.A.sup.c] is a fuzzy soft residual set in (U, E, [psi]).
Let [G.sub.B] be a fuzzy soft residual set in (U, E, [psi]).
Then A is called a neutrosophic residual set in (X, T).
(iii) Ncl(B) = [1.sub.N], for every neutrosophic residual set B in (X, t).
