Fuzzy topological invariants in uniform fuzzy graphs

Journal of Intelligent & Fuzzy Systems, 2023
 In this paper, we have defined some fuzzy topological invariants for particular types of uniform fuzzy graph. Some particular useful types of uniform fuzzy graphs are Uniform Edge Fuzzy Graph, Uniform Vertex Fuzzy Graph, Uniform Vertex-Edge Fuzzy Graph and Totally Uniform Fuzzy Graph. For each particular type we have defined different kinds of degrees

Topological Theory of Fuzziness

1999
The intention of this article is to show how fuzzy set theory fits into classical topology. The basic concepts are filter and ideal bases and morphisms on these. Filter bases are used to define abstract distances. Then compositions and comparisons of filter and ideal bases are considered and uniform neighborhood measures between such bases are ...

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.

Fuzzy rough sets, fuzzy preorders and fuzzy topologies

Fuzzy Sets and Systems, 2013
This paper shows that observations made by different authors at different times regarding one-to-one correspondence between the family of fuzzy preorders on a nonempty set and the family of all fuzzy topologies on this set satisfying certain extra conditions are essentially equivalent.

A new model of fuzzy topology: I -fuzzy topological polygroups

Journal of Intelligent & Fuzzy Systems, 2018
This paper provides a new connection between algebraic hyperstructures and fuzzy sets. We present the concept of I -fuzzy topological polygroups and prove some properties. The concept of I -fuzzy topological polygroups is a generalization of the concept

On extensions of fuzzy topologies

Kybernetika, 1992
Summary: We introduce the concept of extension of fuzzy topologies. If \((X,T)\) is a fuzzy topological space having the property `\(P\)' we find conditions under which the extension of \(T\) will also have the same property `\(P\)'.

Maximal fuzzy topologies

Kybernetika, 1995
Summary: We introduce and study maximal fuzzy \(P\)-spaces where \(P\) is fuzzy Lindelöf, fuzzy countably compact, fuzzy compact, fuzzy lightly compact or fuzzy strongly compact. Characterizations are given for maximal fuzzy \(P\)-spaces where \(P\) is fuzzy Lindelöf, fuzzy countably compact, fuzzy compact, or fuzzy strongly compact.
