Contributions to the coupled coincidence point problem in b-metric spaces with applications


Adrian Petrusel, Gabriela Petrusel, Jen Chin Yao




The aim of this paper is to present, in the context of b-metric spaces, coupled coincidence point theorems under some contraction type conditions. The method is based on the application of some coincidence point theorems of Ran-Reurings type in ordered b-metric spaces. Some applications will illustrate the theory. The approach is new even for the case of usual metric spaces.
