The fuzzy topological spaces on a fuzzy space

Fuzzy Sets and Systems, 1999
The author proposes a definition of fuzzy topology. In this definition a notion of fuzzy topology is considered on a fuzzy subspace [\textit{K. A. Dib}, Inf. Sci. 80, No. 3-4, 253-282 (1994; Zbl 0832.20088)] as a collection of fuzzy subspaces satisfying conditions similar to Chang-fuzzy topology [\textit{C. L. Chang}, J. Math. Anal. Appl.

On intuitionistic fuzzy topological spaces

Kybernetes, 2006
PurposeIn 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 ...

Quotient fuzzy topological spaces

Fuzzy Sets and Systems, 2001
The author proves that a continuous function \(f\) which maps a topological space \((X,\tau)\) to another topological space \((Y,\eta)\) is a quotient map if and only if \(f:(X,\omega(\tau))\to (Y,\omega (\eta))\) is a quotient map, where \(\omega\) denotes the Lowen functor from the category of topological spaces to that of fuzzy topological spaces ...

Fuzzy Topological Spaces Generated by Fuzzy Digraphs

New Mathematics and Natural Computation
In this paper, we defined various fuzzy topological spaces on fuzzy digraph and study interrelation between them. Using adjacency relation on fuzzy vertices and fuzzy edges of fuzzy digraph we defined, namely two types of fuzzy topologies, left(right) fuzzy vertex topology and left(right) fuzzy edge topology on fuzzy digraph, respectively.
