Fixed Point Results for a Selected Class of Multi-Valued Mappings under (θ,)-Contractions with an Application

open access: yesMathematics, 2020
In this article, we introduce a relatively new concept of multi-valued ( θ , R ) -contractions and utilize the same to prove some fixed point results for a special class of multi-valued mappings in metric spaces endowed with an amorphous binary ...

Relational Contractions Involving Shifting Distance Functions with Applications to Boundary Value Problems

open access: yesAxioms, 2023
This manuscript includes certain results on fixed points under a generalized contraction involving a pair of shifting distance functions in the framework of metric space endowed with a class of transitive relation.

A Relation-Theoretic Matkowski-Type Theorem in Symmetric Spaces

open access: yesAxioms, 2021
In this paper, we present a fixed-point theorem in R-complete regular symmetric spaces endowed with a locally T-transitive binary relation R using comparison functions that generalizes several relevant existing results.

Binary relations in the space of binary relations. I. [PDF]

open access: yesApplied Mathematical Sciences, 2014
This article formulates principles of extension, saturation and convergence, and shows how to implement them. In socio-economic systems, there are "reference groups", with the indicators of which the results of the research and experimentation are compared.

Relation theoretic metrical fixed point results for Suzuki type $\mathcal{Z_\mathcal{R}}$-contraction with an application

open access: yesAIMS Mathematics, 2020
In this paper, we introduce the concept of Suzuki type $\mathcal{Z_\mathcal{R}}$-contraction by unifying the definitions of Suzuki type $\mathcal{Z}$-contraction and $\mathcal{Z_\mathcal{R}}$-contraction and also provide examples to highlight the ...

Quasiuniversal properties of neutron star mergers [PDF]

open access: yes, 2014
Binary neutron star mergers are studied using nonlinear 3+1 numerical relativity simulations and the analytical effective-one-body (EOB) model. The EOB model predicts quasiuniversal relations between the mass-rescaled gravitational wave frequency and the

ALGORITHMIZATION OF PROCEDURES FOR COORDINATION INDIVIDUAL OPINIONS IN THE PROCESS OF IMPLEMENTATION ORGANIZATIONAL AND MANAGERIAL LABOR RELATIONS

open access: yesФінансово-кредитна діяльність: проблеми теорії та практики, 2020
The methods of making a collective decision and choosing group matching procedures are analyzed. It is assumed that the methods of evaluation are given in the scales of qualitative order, including the binary relations of alternatives.

A novel pessimistic multigranulation roughness by soft relations over dual universe

open access: yesAIMS Mathematics, 2023
A multigranulation rough set over two universes delivers a unique perspective on the combination of multigranulation information. This paper presents the pessimistic multignualtion rough set over dual universes based on soft binary relations.
