Coupled coincidence point results for (ψ,φ) -weakly contractive mappings in partially ordered Gb-metric spaces

Abstract

In this paper we present some coupled coincidence point results for (ψ,φ) -weakly contractive mappings in the setup of partially ordered Gb -metric spaces. Our results extend the results of Cho et al. (Fixed Point Theory Appl. 2012:8, 2012) and the results of Choudhury and Maity (Math. Comput. Model. 54:73-79, 2011). Moreover, examples of the main results are given.
