A Benchmark Similarity Measures for Fermatean Fuzzy Sets

open access: yesBulletin of the Section of Logic, 2022
In this paper, we utilized triangular conorms (S-norm). The essence of using S-norm is that the similarity order does not change using different norms.

I-convergent triple fuzzy normed spaces

open access: yesProyecciones (Antofagasta), 2022
In this paper we introduce the lacunary ideal convergence of triple sequences in fuzzy normed spaces and the relation between lacunary convergence and lacunary ideal convergence is investigated for triple sequences in fuzzy normed spaces. Concept of limit point and cluster point for triple sequences in fuzzy normed spaces and theorems related to these ...

Approximate Fixed Point Theorems in Fuzzy Norm Spaces for an Operator

open access: yesAdvances in Fuzzy Systems, 2013
We define approximate fixed point and fuzzy diameter in fuzzy norm spaces. We prove theorems for various types of well-known generalized contractions on fuzzy norm spaces with the use of two general lemmas that are given regarding approximate fixed ...

Operator’s Fuzzy Norm and Some Properties

open access: yesFuzzy Information and Engineering, 2015
In this paper, a concept of operator’s fuzzy norm is introduced for the first time in general t-norm setting. Ideas of fuzzy continuous operators, fuzzy bounded linear operators are given with some properties of such operators studied in this general ...

Triangular norms which are join-morphisms in 3-dimensional fuzzy set theory [PDF]

open access: yes, 2013
The n-dimensional fuzzy sets have been introduced as a generalization of interval-valued fuzzy sets, Atanassov's intuitionistic and interval-valued intuitionistic fuzzy sets.

Intuitionistic anti fuzzy normed ideals [PDF]

open access: yesNotes on Intuitionistic Fuzzy Sets, 2021
In this paper, we introduce the notion of intuitionistic anti fuzzy normed subrings and intuitionistic anti fuzzy normed ideals and various properties of intuitionistic anti fuzzy normal subrings and ideals are examined. Also, we prove that the intersection of two intuitionistic anti fuzzy normed ideals is also an intuitionistic anti fuzzy normed ideal.

The Intuitionistic Fuzzy Normed Space of Coefficients

open access: yesAbstract and Applied Analysis, 2012
Intuitionistic fuzzy normed space is defined using concepts of t-norm and t-conorm. The concepts of fuzzy completeness, fuzzy minimality, fuzzy biorthogonality, fuzzy basicity, and fuzzy space of coefficients are introduced. Strong completeness of fuzzy
