Statistical convergence on L−fuzzy normed space

open access: yesFilomat, 2023
In this paper, we study the concept of statistical convergence on L?fuzzy normed spaces. Then we give a useful characterization for statistically convergent sequences. Furthermore, we illustrate that our method of convergence is more general than the usual convergence on L?fuzzy normed spaces.

The Hahn-Banach Extension Theorem for Fuzzy Normed Spaces Revisited [PDF]

open access: yesAbstract and Applied Analysis, 2014
This paper deals with fuzzy normed spaces in the sense of Cheng and Mordeson. We characterize fuzzy norms in terms of ascending and separating families of seminorms and prove an extension theorem for continuous linear functionals on a fuzzy normed space.

n-Tuplet Coincidence Point Theorems in Intuitionistic Fuzzy Normed Spaces [PDF]

open access: yesJournal of Function Spaces, 2014
For an arbitrary n positive integer, we investigate the existence of n-tuplet coincidence points in intuitionistic fuzzy normed space. Results of the paper are more general than those of the coupled and the tripled fixed point works in intuitionistic ...

Browder's Fixed Point Theorem and Some Interesting Results in Intuitionistic Fuzzy Normed Spaces [PDF]

open access: yesFixed Point Theory and Applications, 2010
We define and study Browder's fixed point theorem and relation between an intuitionistic fuzzy convex normed space and a strong intuitionistic fuzzy uniformly convex normed space.

Bernstein Approximations for Fuzzy-Valued Functions

open access: yesMathematics
Studying the Bernstein approximations for fuzzy functions is a new attempt. With the help of considering the support functions of fuzzy sets in which the weak* topology for the normed dual space is involved, we are able to approximate continuous fuzzy ...

The Study of Felbin and $BS$ Fuzzy Normed Linear Spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2022
In this paper, we first show that the  induced topologies by Felbin and Bag-Samanta type fuzzy norms on a linear space $X$ are equivalent. So all results in Felbin-fuzzy normed linear spaces are valid in Bag-Samanta fuzzy normed linear spaces and vice ...

Properties of the Adjoint Operator of a General Fuzzy Bounded Operator

open access: yesمجلة بغداد للعلوم, 2021
Our goal in the present paper is to recall the concept of general fuzzy normed space and its basic properties in order to define the adjoint operator of a general fuzzy bounded operator from a general fuzzy normed space V into another general fuzzy ...

Fuzzy Convergence Sequence and Fuzzy Compact Operators on Standard Fuzzy Normed Spaces

open access: yesمجلة بغداد للعلوم, 2021
The main purpose of this work is to introduce some types of fuzzy convergence sequences of operators defined on a standard fuzzy normed space (SFN-spaces) and investigate some properties and relationships between these concepts.

Completeness of the Cartesian Product of Two Complete Fuzzy Normed Spaces [PDF]

open access: yesEngineering and Technology Journal, 2013
In this paper it was proved that the Cartesian product of two fuzzy normed spaces is a fuzzy normed space then it was proved that the Cartesian product of two complete fuzzy normed spaces is again a complete fuzzy normed space.

Best approximations of the ϕ-Hadamard fractional Volterra integro-differential equation by matrix valued fuzzy control functions

open access: yesAdvances in Difference Equations, 2021
In this article, first, we present an example of fuzzy normed space by means of the Mittag-Leffler function. Next, we extend the concept of fuzzy normed space to matrix valued fuzzy normed space and also we introduce a class of matrix valued fuzzy ...
