Positive coincidence points for a class of nonlinear operators and their applications to matrix equations

Open Mathematics, 2020
Consider an ordered Banach space and f,gf,g two self-operators defined on the interior of its positive cone. In this article, we prove that the equation f(X)=g(X)f(X)=g(X) has a positive solution, whenever f is strictly α\alpha -concave g-monotone or ...

A General Approach to Wardowski Type Contractions in Generalized Metric Spaces and Applications

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we study F‐contractions in the setting of generalized metric spaces and introduce a novel concept of unified generalized F‐weak contractions for self‐mappings. We establish existence and uniqueness results for fixed points associated with this class of contractive mappings.

Ordered Bipolar Metric Spaces and Fixed‐Point Results With an Application to Solution of Fractional Differential Equations

Journal of Mathematics, Volume 2026, Issue 1, 2026.
The aim of this paper is to introduce the concept of an ordered bipolar metric space in which we establish some fixed‐point theorems for contravariant mappings under a generalized nonlinear rational‐type contractive condition. Moreover, we analyze the monotonicity of the second iteration of the mapping, which is inherently covariant.

Fixed point results for contractions of polynomial type

Demonstratio Mathematica
We introduce two new classes of single-valued contractions of polynomial type defined on a metric space. For the first one, called the class of polynomial contractions, we establish two fixed point theorems.

Dislocated quasi cone b-metric space over Banach algebra and contraction principles with application to functional equations

Open Mathematics, 2019
In this paper we introduce dislocated and dislocated quasi version of a cone b-metric space over a Banach algebra as well as weak semi α-admissible and α-identical pair of mappings and prove common fixed point theorems for a pair of α-identical and weak ...

Extensions of Well‐Known Fixed‐Point Theorems to Quasi M‐Metric Spaces With Applications

Journal of Mathematics, Volume 2026, Issue 1, 2026.
Fixed‐point theory has become a frequently studied topic due to its various applications in both metric spaces and generalized metric spaces. The fact that each study leads to new research also increases the importance of studying this theory. Under this perspective, the concept of quasi M‐metric spaces, which is an example of a generalized metric ...
