Fixed-Point Study of Generalized Rational Type Multivalued Contractive Mappings on Metric Spaces with a Graph
(MDPI, 2021-03-11)
The main result of this paper is a fixed-point theorem for multivalued contractions obtained through an inequality with rational terms. The contraction is an F-type contraction. The results are obtained in a metric space ...
e-Distance in Menger PGM Spaces with an Application
(MDPI, 2020-12-30)
The main purpose of the present paper is to define the concept of an e-distance (as a generalization of r-distance) on a Menger PGM space and to introduce some of its properties. Moreover, some coupled fixed point results, ...
Highlighting the Compound Risk of COVID-19 and Environmental Pollutants Using Geospatial Technology
(Nature, 2021-04-16)
The new COVID-19 coronavirus disease has emerged as a global threat and not just to human health but also the global economy. Due to the pandemic, most countries affected have therefore imposed periods of full or partial ...
Optimal Perturbation Iteration Method for Solving Fractional Model of Damped Burgers’ Equation
(MDPI, 2020-06-04)
The newly constructed optimal perturbation iteration procedure with Laplace transform is applied to obtain the new approximate semi-analytical solutions of the fractional type of damped Burgers’ equation. The classical ...
Some New Fuzzy Fixed Point Results with Applications
(MDPI, 2020-06-17)
The aim of this article is to establish some fixed point results for fuzzy mappings and derive some corresponding multivalued mappings results of literature. For this purpose, we define some new and generalized contractions ...
On the Topology Induced by C*-Algebra-Valued Fuzzy Metric Spaces
(MDPI, 2020-06-03)
We define the notion of <inline-formula> <math display="inline"> <semantics> <msup> <mi>C</mi> <mo>*</mo> </msup> </semantics> </math> </inline-formula>-algebra-valued fuzzy metric spaces and we study the topology induced ...
Applying Fixed Point Techniques to Stability Problems in Intuitionistic Fuzzy Banach Spaces
(MDPI, 2020-06-15)
In this paper we investigate Hyers-Ulam-Rassias stability of certain nonlinear functional equations. Considerations of such stabilities in different branches of mathematics have been very extensive. Again the fuzzy concepts ...
Some New Results on Coincidence Points for Multivalued Suzuki-Type Mappings in Fairly Complete Spaces
(MDPI, 2020-03-17)
In this paper, we introduce Suzuki-type generalized and modified proximal contractive mappings. We establish some coincidence and best proximity point results in fairly complete spaces. Also, we provide coincidence and ...
New Fixed Point Theorems in Orthogonal F -Metric Spaces with Application to Fractional Differential Equation
(MDPI, 2020-05-19)
We present the notion of orthogonal F
-metric spaces and prove some fixed and periodic point theorems for orthogonal ⊥Ω
-contraction. We give a nontrivial example to prove the validity of our result. Finally, as ...
Stability Analysis and Optimal Control of a Fractional Order Synthetic Drugs Transmission Model
(MDPI, 2021-03-24)
In this work, a fractional-order synthetic drugs transmission model with psychological addicts has been proposed along with psychological treatment. The effects of synthetic drugs are deadly and sometimes even violent. We ...
