Solving a Boundary Value Problem via Fixed-Point Theorem on ®-Metric Space.

In this paper, we prove the fixed-point theorem for rational contractive mapping on ®-metric space. Additionally, an Euclidean metric space with a binary relation example and an application to the first-order boundary value problem are given. Moreover, the obtained results generalize and extend some of the well-known results in the literature. [ABSTRACT FROM AUTHOR]
