Common tripled fixed point theorem in two rectangular b-metric spaces and applications

In this paper, we establish some new common tripled fixed point theorems for mappings defined on a set equipped with two rectangular b-metrics. We also provide illustrative examples in support of our new results. In the end of the paper, we give an existence and uniqueness theorem for a class of nonlinear integral equations by using the obtained result. The results presented in this paper generalize the well-known comparable results in the literature.
