On intuitionistic fuzzy topological spaces
Kybernetes, 2006PurposeIn 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 ...

On intuitionistic fuzzy rough sets and their topological structures
International Journal of General Systems, 2009In this paper, lower and upper approximations of intuitionistic fuzzy sets with respect to an intuitionistic fuzzy approximation space are first defined. Properties of intuitionistic fuzzy approximation operators are examined. Relationships between intuitionistic fuzzy rough set approximations and intuitionistic fuzzy topologies are then discussed.

Intuitionistic Fuzzy Topologies in Crisp Approximation Spaces
2012A rough intuitionistic fuzzy set is the result of approximation of an intuitionistic fuzzy set with respect to a crisp approximation space. In this paper, we investigate topological structures of rough intuitionistic fuzzy sets. We examine that a reflexive crisp rough approximation space can induce an intuitionistic fuzzy Alexandrov space. It is proved

Intuitionistic fuzzy topological operators and topology
2004The introduction of intuitionistic fuzzy sets is due to K.T. Atanassov who, also, defined various topological operators for these sets. D. Çoker defined the intuitionistic fuzzy topological spaces. In this paper we show relations between Atanassov’s topological operators and Çoker's intuitionistic fuzzy topology.

Intuitionistic Fuzzy Weakly Contra Open Mappings in Intuitionistic Fuzzy Topological Spaces
Asian Journal of Research in Social Sciences and Humanities, 2016In this paper, we introduce intuitionistic fuzzy weakly contra open mappings in intuitionistic fuzzy topological spaces. We study some of their properties and obtain their characterizations. Relationship between this new class and other classes of functions are established in intuitionistic fuzzy topological spaces.

Hausdorffness in intuitionistic fuzzy topological spaces
2004The basic concepts of the theory of intuitionistic fuzzy topological spaces have been defined by D. Çoker and co-workers. In this paper, we define new notions of Hausdorffness in the intuitionistic fuzzy sense, and obtain some new properties, in particular on ...

Separation in intuitionistic fuzzy topological spaces
2004The basic concepts of the theory of intuitionistic fuzzy topological spaces have been defined by D. Çoker and co-workers. In a recent paper, we define two notions of Hausdorffness in the intuitionistic fuzzy sense, and obtain some new properties. In this paper we introduce normality and regularity in the intuitionistic fuzzy sense and obtain relations ...
