Energy Source Allocation Decision‐Making in Textile Industry: A Novel Symmetric and Asymmetric Spherical Fuzzy Linear Optimization Approach

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
In this study, the authors extended the concept of spherical fuzzy optimization models by considering different parameters of spherical fuzzy linear programming problem as symmetric and asymmetric spherical numbers. Eight spherical fuzzy linear programming models are discussed by converting decision variables, parameters, and coefficients of objective ...

Common Coupled Fixed Point Theorems on C⋆‐Algebra‐Valued Partial Metric Spaces

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
In this paper, we prove common coupled fixed point theorems on complete C⋆‐algebra‐valued partial metric spaces. An example and application to support our result are presented.

[Retracted] Semigroup of Finite‐State Deterministic Intuitionistic Fuzzy Automata with Application in Fault Diagnosis of an Aircraft Twin‐Spool Turbofan Engine

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
The twin‐spool turbofan engine is an important component of almost every modern aircraft. Fault detection at an early stage can improve engine performance and health. The current research is based on the construction of an inference system for fault diagnosis in a generalized fuzzy environment.

Fuzzy Product KM‐Subalgebras and Some Related Properties

Complexity, Volume 2021, Issue 1, 2021., 2021
The concept of KM‐algebras has been originated in 2019. KM‐algebra is a generalization of some of the B‐algebras such as BCK, BCI, BCH, BE, and BV and also d‐algebras. KM‐algebra serves two purposes in mathematics and computer science as follows: a tool for application in both fields and a strategy for creating the foundations.

Solving a Split Feasibility Problem by the Strong Convergence of Two Projection Algorithms in Hilbert Spaces

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
The goal of this manuscript is to establish strong convergence theorems for inertial shrinking projection and CQ algorithms to solve a split convex feasibility problem in real Hilbert spaces. Finally, numerical examples were obtained to discuss the performance and effectiveness of our algorithms and compare the proposed algorithms with the previous ...

On Complex‐Valued Triple Controlled Metric Spaces and Applications

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
In this manuscript, we introduce the concept of complex‐valued triple controlled metric spaces as an extension of rectangular metric type spaces. To validate our hypotheses and to show the usability of the Banach and Kannan fixed point results discussed herein, we present an application on Fredholm‐type integral equations and an application on higher ...

On Controlled Rectangular Metric Spaces and an Application

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
In this paper, we introduce the notion of controlled rectangular metric spaces as a generalization of rectangular metric spaces and rectangular b‐metric spaces. Further, we establish some related fixed point results. Our main results extend many existing ones in the literature. The obtained results are also illustrated with the help of an example.

Numerical Scheme for Finding Roots of Interval‐Valued Fuzzy Nonlinear Equation with Application in Optimization

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
In this research article, we propose efficient numerical iterative methods for estimating roots of interval‐valued trapezoidal fuzzy nonlinear equations. Convergence analysis proves that the order of convergence of numerical schemes is 3. Some real‐life applications are considered from optimization as numerical test problems which contain interval ...

Exciting Fixed Point Results on a Novel Space with Supportive Applications

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
The goal of this paper is to present a new space, a complex valued controlled rectangular b‐metric space (for short, υℂ‐metric space). Some examples and topological properties of υℂ‐metric spaces are given. Also, some related common fixed point results are discussed. Our results generalize a lot of works in this direction.

A Reliable Treatment for Nonlinear Differential Equations

Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021
In this paper, we use the concept of homotopy, Laplace transform, and He’s polynomials, to propose the auxiliary Laplace homotopy parameter method (ALHPM). We construct a homotopy equation consisting on two auxiliary parameters for solving nonlinear differential equations, which switch nonlinear terms with He’s polynomials.
