Math. Comp. Sc., 20, 82–97, 2024), Raji and Ibrahim introduced a new class of contractions, termed modified α-<em>F</em>-weak contractions, and established fixed point results in complete metric spaces, thereby extending the classical Banach contraction principle. Building on this, the present paper introduces an extended <em>F</em>-weak contraction mapping in ordered metric spaces and derives corresponding fixed-point results. The theoretical contributions are further illustrated through numerical examples. As an application, we demonstrate the existence and uniqueness of solutions to a first-order ordinary differential equation subject to periodic boundary conditions.</p> <p><strong>Mathematics subject Classification</strong>&nbsp;&nbsp; 47H10; 54H25</p> 2026-07-20T00:00:00+00:00 ##submission.copyrightStatement##
