The idea of intuitionistic fuzzy nowhere dense set in intuitionistic fuzzy topological space presented and studied by by Dhavaseelan and et al.

11] If A is a neutrosophic nowhere dense set in (X, T), then [bar.

N], then A is a neutrosophic nowhere dense set in (X, T).

It is known that for an almost continuous function f with a dense graph, every

nowhere dense set is f-negligible with respect to AC (see [13]).

A Fuzzy topological space (X, T) is called a Fuzzy nodec space if every non-zero Fuzzy nowhere dense set is Fuzzy closed in (X, T).

i] be a Fuzzy nowhere dense set in a Fuzzy nodec space (X, T).

If [lambda][less than or equal to][mu] and [mu] is a Fuzzy nowhere dense set in a Fuzzy topological space (X, T), then [lambda] is also a Fuzzy nowhere dense set in (X, T).

The NC[alpha]-open with respect to a given neutrosophic crisp topology are exactly those sets which may be written as a difference between a neutrosophic crisp open set and neutrosophic crisp nowhere dense set

C]) clearly is neutrosophic crisp nowhere dense set, we easily see that B [subset] NCcl (NC int(A)) and consequently A [subset] B [subset] NC int(NCcl (NC int(A)) so the proof is complete.

To point out the difference between (q)-porous and

nowhere dense sets, note that if E [subset] Y is nowhere dense, y [member of]Y and r > 0, then there are a point z [member of] Y and a number s > 0 such that B(z,s) [subset] B(y,r) E.

In fact, if lattice DP(X) is isomorphic to lattice DP(Y) then we obtain a bijective map F: X [right arrow] Y preserving closed nowhere dense sets, which turns out to be a homeomorphism if X and Y are countably compact T3 spaces without isolated points.

We show here that for a Hausdorff space X without isolated points there is a bijection from [LAMBDA] onto X which maps [LAMBDA]-closed sets in [LAMBDA] to closed nowhere dense sets in X.
