A technique of tripled coincidence points for solving a system of nonlinear integral equations in POCML spaces [PDF]

open access: goldJournal of Inequalities and Applications, 2020
This manuscript aims to initiate some recent theoretical consequences related to tripled coincidence points for non-self mappings via the notion of C-type functions in partially ordered complete metric-like space (for short, POCML space).

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

open access: yesAIMS 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

Fixed points and coincidence points for multimaps with not necessarily bounded images [PDF]

open access: goldFixed Point Theory and Applications, 2004
In metric spaces, single-valued self-maps and multimaps with closed images are considered and fixed point and coincidence point theorems for such maps have been obtained without using the (extended) Hausdorff metric, thereby generalizing many results in ...

Coincidence and common fixed points for F-Contractive mappings

open access: goldAnnals of Mathematics and Physics, 2023
The purpose of this article is to establish the existence and uniqueness of coincidence and common fixed point of discontinuous non-compatible faintly compatible pair of self maps in non-complete metric space without using containment requirement of ...

Untwining multiple parameters at the exclusive zero-coincidence points with quantum control [PDF]

open access: greenNew Journal of Physics, 2022
In this paper we address a special case of ‘sloppy’ quantum estimation procedures which happens in the presence of intertwined parameters. A collection of parameters are said to be intertwined when their imprinting on the quantum probe that mediates the ...

New Nonlinear Conditions and Inequalities for the Existence of Coincidence Points and Fixed Points [PDF]

open access: goldJournal of Applied Mathematics, 2012
Some new fixed point theorems for nonlinear maps are established. By using these results, we can obtain some new coincidence point theorems. Our results are quite different in the literature and references therein.

On almost coincidence points in generalized convex spaces [PDF]

open access: goldFixed Point Theory and Applications, 2006
We prove an almost coincidence point theorem in generalized convex spaces. As an application, we derive a result on the existence of a maximal element and an almost coincidence point theorem in hyperconvex spaces.

Some New Results on Coincidence Points for Multivalued Suzuki-Type Mappings in Fairly Complete Spaces [PDF]

open access: goldDe Computis, 2020
In this paper, we introduce Suzuki-type ( α , β , γ g ) - generalized and modified proximal contractive mappings. We establish some coincidence and best proximity point results in fairly complete spaces.
