Abstract

In this paper, we introduce the notion of G-rational Geraghty contractive mappings in the setup of ordered generalized b-metric spaces and investigate the existence of fixed points for such mappings. We also provide an example to illustrate the presented results and show that they are more general then some existing ones.
