On Strong Coupled Coincidence Points of g-Couplings and an Application [PDF]

Journal of Function Spaces, 2018
The purpose of this paper is to prove the existence and uniqueness of a strong coupled coincidence point of F:X×X→X and g:X→X, involving Banach and Chatterjea type g-couplings.

About coincidence points theorems on 2-step Carnot groups with 1-dimensional centre equipped with Box-quasimetrics

AIMS Mathematics, 2023
For some class of 2-step Carnot groups $ D_n $ with 1-dimensional centre we find the exact values of the constants in $ (1, q_2) $-generalized triangle inequality for their $ \text{Box} $-quasimetrics $ \rho_{\text{Box}_{D_n}} $. Using this result we get

Coincidence points of mappings in Banach spaces [PDF]

Fixed Point Theory, 2020
In this article we prove an existence theorem for coincidence points of mappings in Banach spaces. This theorem generalizes the Kantorovich fixed point theorem.

MAPS PRESERVING THE COINCIDENCE POINTS OF OPERATORS

EURASIAN MATHEMATICAL JOURNAL, 2021
Summary: Let \(\mathcal{B(X)}\) be the algebra of all bounded linear operators on a Banach space \(\mathcal{X}\) with \(\dim \mathcal{X} \geqslant 2\). In this paper, we describe surjective maps \(\phi: \mathcal{B(X)}\to\mathcal{B(X)}\) preserving the coincidence points of operators, i.e., \(C(A,B)=C(\phi(A),\phi(B))\), for every \(A, B \in \mathcal{B ...

A novel approach to coincidence point results via proximal contractions with application [PDF]

Scientific Reports
In this manuscript, we established coincidence point theory by using F-contractions within complete extended suprametric spaces. The results about coincidence points involve $$(F_{\mathbb {C}_{P}})_{\tau }$$ -proximal contractions together with rational $

Coincidence and fixed points for compatible and relatively nonexpansive maps [PDF]

International Journal of Mathematics and Mathematical Sciences, 1993
The concept of relatively nonexpansive maps is introduced. Fixed point and coincidence results for families of four self maps of metric spaces are obtained.

Simulation type functions and coincidence points

Filomat, 2018
In this paper, we obtain some sufficient conditions for the existence and uniqueness of point of coincidence by using simulation functions in the context of metric spaces and prove some interesting results. Our results generalize the corresponding results of [5, 8, 13, 14, 16] in several directions.

New Existence Results and Generalizations for Coincidence Points and Fixed Points without Global Completeness

Abstract and Applied Analysis, 2013

Zeros of conic functions, fixed points and coincidences

Doklady Mathematics
Concept of conic function with operator coefficients is introduced. Zero existence theorem is proved for such functions. On this basis, fixed point theorem is obtained, for a multivalued self-mapping of a conic metric space, generalizing the recent fixed point theorem by E.S. Zhukovsky and E.A.
