C-Class Akram and Generalized MJ contractions guarantee unique fixed and common fixed point convergence in metric spaces.– Omidire et al. 2025

This study focuses on approximating fixed points under novel contractivity conditions in metric spaces. It introduces two new types of contractivity conditions: C-Class Akram Contraction and C-Class Generalized MJ Contraction. The authors establish the convergence of Picard and Jungck iterations toward unique fixed points and unique common fixed points, respectively. Fixed point theory is a fundamental tool in mathematics, engineering, and other fields, as it helps solve complex nonlinear mathematical problems, such as optimization and differential equations. The study generalizes and extends several existing results in fixed point theory, incorporating concepts such as altering distance functions and C-class functions.

How the Study was Conducted

The study employed mathematical analysis and iterative methods within the framework of fixed point theory to introduce and investigate two novel contractivity conditions—C-Class Akram Contraction and C-Class Generalized MJ Contraction. By generalizing existing fixed point results, the researchers formulated new mathematical definitions and explored their properties in metric spaces.
To validate their findings, the authors utilized rigorous proof techniques to establish the existence and uniqueness of fixed points under these new contractivity conditions. The authors also analyzed the convergence behavior of Picard and Jungck iterative schemes, demonstrating that these processes reliably approximated unique fixed points. Furthermore, the study included comparative analyses with existing theories, extending classical results and highlighting the improved applicability of the proposed conditions. These combined methods underscore the effectiveness of the new contractivity conditions and mark a meaningful advancement in fixed point approximations.

What the Authors Found

The authors introduced two novel contractivity conditions—C-Class Akram Contraction and C-Class Generalized MJ Contraction—which successfully establish the existence and uniqueness of fixed points and common fixed points in metric spaces. These results generalize and extend several classical fixed point theorems, including those of Banach, Jungck, Kannan, and Akram contractions. Furthermore, they demonstrated that Picard Iteration converges to a unique fixed point under the C-Class Akram Contraction, while Jungck Iteration converges to a unique common fixed point under the C-Class Generalized MJ Contraction. These findings enhance the stability and efficiency of iterative methods in solving nonlinear mathematical problems such as optimization and differential equations.
