Abstract
Purpose
In 2000, Wang and He published an important result on the theory of intuitionistic fuzzy sets (IFSs). Indeed, they showed that every IFS may be regarded as an L‐fuzzy set for some appropriate lattice L. This paper aims to show that, nevertheless, the results obtained by various authors on intuitionistic fuzzy topological spaces (IFTSs), are not redundant with others for the ordinary fuzzy sense.
Design/methodology/approach
The most important definitions and results on intuitionistic fuzzy topology (IFT) one compared with the result obtained by Wang and He.
Findings
That these results are not redundant.
Research limitations/implications
Clearly, this paper is devoted to IFTSs.
Practical implications
The main applications are in the mathematical field.
Originality/value
The originality and value of IFT are here demonstrated.

Abstract
Purpose
In 2005, Smarandache generalized the Atanassov's intuitionistic fuzzy sets (IFSs) to neutrosophic sets (NS), and other researchers introduced the notion of interval neutrosophic set (INSs), which is an instance of NS, and studied various properties. The notion of neutrosophic topology on the non‐standard interval is also due to Smarandache. The purpose of this paper is to study relations between INSs and topology.
Design/methodology/approach
The paper investigates the possible relations between INSs and topology.
Findings
Relations on INSs and neutrosophic topology.
Research limitations/implications
Clearly, the paper is confined to IFSs and NSs.
Practical implications
The main applications are in the mathematical field.
Originality/value
The paper shows original results on fuzzy sets and topology.

Abstract
Purpose
Recently, F. Smarandache generalized the Atanassov's intuitionistic fuzzy sets and other kinds of sets to neutrosophic sets (NSs). Also, this author introduced a general definition of neutrosophic topology. On the other hand, there exist various kinds of paraconsistent logics, where some contradiction is admissible. The purpose of this paper is to show that a Smarandache's definition of neutrosophic paraconsistent topology is not a generalization of Çoker's intuitionistic fuzzy topology (IFT) or Smarandache's general neutrosophic topology.
Design/methodology/approach
The possible relations between the IFT and the neutrosophic paraconsistent topology are studied.
Findings
Relations on IFT and neutrosophic paraconsistent topology are shown.
Research limitations/implications
Clearly, the paper is confined to IFSs and NSs.

Recently, Smarandache generalized the Atanassov's intuitionistic fuzzy sets (IFSs) and other kinds of sets to neutrosophic sets (NSs). Also, this author defined the notion of neutrosophic topology on the non‐standard interval.

Relations on neutrosophic topology and IFT are found.
