Coincidence and Common Fixed Point Theorems via ϱ-Class Functions in Elliptic Valued Metric Spaces

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021
The main goal of this study is to define a new metric space which is a generalization of complex valued metric spaces introduced by Azam et al.

Collectively Fixed Point Theory in the Compact and Coercive Cases

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
We present collectively fixed point results for multivalued maps which automatically generate analytic alternatives and minimax inequalities. As an application we consider equilbrium type problems for generalized games.

Global optimum solutions for a system of (k, ψ)-Hilfer fractional differential equations: Best proximity point approach

Demonstratio Mathematica, 2023
In this article, a class of cyclic (noncyclic) operators are defined on Banach spaces via concept of measure of noncompactness using some abstract functions. The best proximity point (pair) results are manifested for the said operators. The obtained main

Mann-Dotson's algorithm for a countable family of non-self Lipschitz mappings in hyperbolic metric space

Topological Algebra and its Applications, 2023
The aim of this article is to present some Δ\Delta -convergence and strong convergence results for a countable family of non-self mappings. More precisely, we employ Mann-Dotson’s algorithm to approximate, common fixed points of a countable family of non-

Remarks on some coupled coincidence point results in partially ordered metric spaces

Arab Journal of Mathematical Sciences, 2014
In this paper we have used a method of reducing coupled coincidence and coupled fixed point results in partially ordered metric spaces to the respective results for mappings with one variable, even obtaining (in some cases) more general theorems.

Some fixed point results on Ultrametric Space

Topological Algebra and its Applications, 2022
The present paper deals with new fixed point theorems by means of F−contraction. The results are present in spherically complete ultrametric space for single valued rational type mappings.

Fixed point results for multivalued mappings of Ćirić type via F-contractions on quasi metric spaces

Open Mathematics, 2020
In this paper, we present some fixed point results for multivalued mappings with both closed values and proximinal values on left K-complete quasi metric spaces. We also provide a nontrivial example to illustrate our results.

A new solution to the Rhoades’ open problem with an application

Acta Universitatis Sapientiae: Mathematica, 2021
We give a new solution to the Rhoades’ open problem on the discontinuity at fixed point via the notion of an S-metric. To do this, we develop a new technique by means of the notion of a Zamfirescu mapping.
