A new approach to fuzzy bitopological spaces

Information Sciences, 2001
Corresponding to a given fuzzy bitopological space \((X,\tau_1,\tau_2)\), the author introduces a supra-fuzzy topology \(\tau_s\) which is generated by a supra-fuzzy closure operator [the author with \textit{A. Kandil} and \textit{A. A. Nouh}, Fuzzy Sets Syst. 74, No.

Fuzzy quasi uniformities and fuzzy bitopological spaces

Fuzzy Sets and Systems, 1992
This paper considers bitopological spaces in fuzzy setting along with some separation axioms. The authors consider the previously introduced concept of quasi-uniformity and establish that a fuzzy bitopological space is fuzzy quasi-uniformizable if and only if it is pairwise completely regular.

Connectedness of Fuzzy Bitopological Spaces

2006 International Conference on Machine Learning and Cybernetics, 2006
After introducing the definition of separated sets, the connectedness of a fuzzy bitopological space is discussed. A number of results are obtained. Some of them show the connectedness defined here is a "good extension".

Some properties of intuitionistic fuzzy bitopological spaces

The 6th International Conference on Soft Computing and Intelligent Systems, and The 13th International Symposium on Advanced Intelligence Systems, 2012
We introduce the concept of intuitionistic fuzzy bitopological spaces as a generalization of fuzzy bitopological spaces. Next, we introduce different types of open sets in intuitionistic fuzzy bitopological spaces, and investigate some of their basic properties.

Strong and ultra separation axioms of fuzzy bitopological spaces

Fuzzy Sets and Systems, 1999
Given a fuzzy bitopological space \((X,\sigma_1,\sigma_2)\), fuzzy pairwise separation axioms \(\alpha.FPT_i\), \(S.FPT_i\), \(U.FPT_i\) \((i=0,1,2)\), \(\alpha.FPR_k\), \(S.FPR_k\), \(U.FPR_k\) \((k=2,3)\), \(\alpha.FPT_{j+1}\), \(S.FPT_{j +1}\), \(U.FPT_{j+1}\) \((j=2,3)\) are introduced. Defining these concepts, level bitopologies \(\ell_a(\tau_1)\),
