Fuzzy games with a countable space of actions and applications to systems of generalized quasi-variational inequalities [PDF]

open access: yes, 2013
In this paper, we introduce an abstract fuzzy economy (generalized fuzzy game) model with a countable space of actions and we study the existence of the fuzzy equilibrium. As applications, two types of results are obtained.

Fuzzy quasi-b-metric spaces

open access: yesAnnals of West University of Timisoara - Mathematics and Computer Science, 2022
Abstract In this paper we present a new approach for the fuzzy quasi-b-metric spaces and we obtain some properties of these spaces. A special attention is granted to the decomposition theorems of a fuzzy quasi-b-metric into a right continuous and ascending family of quasi-b-metrics.

Fuzzy Semi-Metric Spaces [PDF]

open access: yesMathematics, 2018
The T1-spaces induced by the fuzzy semi-metric spaces endowed with the special kind of triangle inequality are investigated in this paper. The limits in fuzzy semi-metric spaces are also studied to demonstrate the consistency of limit concepts in the induced topologies.

Fuzzy de Sitter Space from kappa-Minkowski Space in Matrix Basis [PDF]

open access: yes, 2019
We consider the Lie group $\mathbb{R}^D_\kappa$ generated by the Lie algebra of $\kappa$-Minkowski space. Imposing the invariance of the metric under the pull-back of diffeomorphisms induced by right translations in the group, we show that a unique right

‎Intuitionistic Fuzzy Modular Spaces [PDF]

open access: yesTransactions on Fuzzy Sets and Systems, 2023
‎After the introduction of the concept of fuzzy sets‎ ‎by Zadeh‎, ‎several researches were conducted on‎ ‎the generalizations of the notion of fuzzy sets‎. ‎There are many viewpoints on the notion of metric space in fuzzy topology‎.

Some Modified Fixed Point Results in V-Fuzzy Metric Spaces

open access: yesAdvances in Fuzzy Systems, 2019
The present research paper focuses on the existence of fixed point in V-fuzzy metric space. The presentation of V-fuzzy metric space in n-tuple encourages us to define different mapping in the symmetric V-fuzzy metric space. Here, the properties of fuzzy

A Strong Law of Large Numbers for Random Sets in Fuzzy Banach Space

open access: yesAdvances in Fuzzy Systems, 2020
The main purpose of this paper is to consider the strong law of large numbers for random sets in fuzzy metric space. Since many years ago, limited theorems have been expressed and proved for fuzzy random variables, but despite the uncertainty in fuzzy ...

Fixed-Point Results Related to b-Intuitionistic Fuzzy Metric Space

open access: yesJournal of Function Spaces, 2022
In this study, we contribute to the terminological debate about various fixed-point results’ use of the term intuitionistic fuzzy b-metric space in defining the structure based on fuzzy sets.
