Intuitionistic Fuzzy Approximation Spaces Induced by Intuitionistic Fuzzy Topologies

2016 Joint 8th International Conference on Soft Computing and Intelligent Systems (SCIS) and 17th International Symposium on Advanced Intelligent Systems (ISIS), 2016
We investigate intuitionistic fuzzy approximation spaces induced by intuitionistic fuzzy topologies, and prove that there exists a one-to-one correspondence between the set of all preordered intuitionistic fuzzy relations and the set of all intuitionistic fuzzy topologies satisfying appropriate condition.

Topology of interval-valued intuitionistic fuzzy sets

Fuzzy Sets and Systems, 2001
The concept of interval-valued intuitionistic fuzzy set (IVIFS) was introduced by the reviewer and \textit{G. Gargov} [Fuzzy Sets Syst. 31, No. 3, 343-349 (1989; Zbl 0674.03017)]. In the present paper one of the possible topologies over IVIFSs is defined and some of its properties are studied.

An introduction to intuitionistic fuzzy topological spaces

Fuzzy Sets and Systems, 1997
The author gives the fundamentals of the theory of intuitionistic fuzzy topological spaces and precisely the concepts of compactness, connectedness and Hausdorffness. Several characterizations are given supported by suitable examples.

Nets and filters in intuitionistic fuzzy topological spaces

Information Sciences, 2006
In this note the author introduces the notions of nets and filters in the sense of intuitionistic fuzzy sets. An intuitionistic fuzzy set is regarded as a pair of membership and non-membership functions \(\langle\mu_A(x), \gamma_A(x)\rangle\) for any \(x\) in \({\mathbf X}\) and \(\mu_A:{\mathbf X}\to [0,1]\), \(\gamma_A:{\mathbf X}\to [0,1]\), where \(

Intuitionistic fuzzy topological operators and topology

open access: yes, 2004
The 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.
