Fixed Point Results on Closed Ball in Convex Rectangular b−Metric Spaces and Applications

In this paper, the concept of convex rectangular b−metric spaces is introduced as a generalization of both convex metric spaces and rectangular b−metric spaces. The purpose of this study is to indicate a way of generalizing Mann’s iteration algorithm and a series of fixed point results in rectangular b−metric spaces. Furthermore, certain examples are given to support the results. We also study well posedness of fixed point problems of some mappings in convex rectangular b−metric spaces, and an application to the dynamic programming is entrusted to manifest the viability of the obtained results. Our results extend comparable results in the existing literature.
