Investigating Novel Types of Coincidence and Quasi‐Coincidence Relations and Studying Equivalent Intuitionistic Fuzzy Sets

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
In this work, we modify the definition of intuitionistic fuzzy points so that the definition is concise, generalizes fuzzy points, and excludes 0˜. We establish new forms of relations between intuitionistic fuzzy sets and demonstrate that every quasi‐coincidence relation is coincidence.

Uniform Continuity in Fuzzy Metric Spaces [PDF]

open access: yes, 2001
With the help of appropriate fuzzy notions of equinormality and Lebesgue property, several characterizations of those fuzzy metric spaces, in the sense of George and Veeramani, for which every real valued continuous function is uniformly continuous ...

Fuzzy r‐continuous and fuzzy r‐semicontinuous maps

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 1, Page 53-63, 2001., 2001
We introduce a new notion of fuzzy r‐interior which is an extension of Chang′s fuzzy interior. Using fuzzy r‐interior, we define fuzzy r‐semiopen sets and fuzzy r‐semicontinuous maps which are generalizations of fuzzy semiopen sets and fuzzy semicontinuous maps in Chang′s fuzzy topology, respectively.

Strong convergence in fuzzy metric spaces [PDF]

open access: yes, 2017
[EN] In this paper we introduce and study the concept of strong convergence in fuzzy metric spaces (X, M,*) in the sense of George and Veeramani. This concept is related with the condition Lambda M-t > 0(x, y, t) > 0, which frequently is required or ...

Fuzziness in Chang's fuzzy topological spaces [PDF]

open access: yes, 1999
It is known that fuzziness within the concept of openness of a fuzzy set in a Chang's fuzzy topological space (fts) is absent. In this paper we introduce a gradation of openness for the open sets of a Chang jts (X, $\mathcal{T}$) by means of a map ...

On the uniformization of L-valued frames [PDF]

open access: yes, 1994
This note discusses the appropriate way of uniformizing the notion of an L-valued frame introduced by A. Pultr and S. Rodabaugh in [Lattice-valued frames, functor categories, and classes of sober spaces, Chapter 6 of Topological and Algebraic ...

Pairwise fuzzy irresolute mappings [PDF]

open access: yes, 1996
summary:In this paper the concepts of fuzzy irresolute and fuzzy presemiopen mappings due to Yalvac [12] are generalized to fuzzy bitopological spaces and their basic properties and characterizations are ...
