Generalization contractive mappings on rectangular \(b\)-metric space (Q2166686)

Summary: In this paper, we introduce new coincidence fixed point theorems for generalized \(\left( \phi , \psi\right)\)-contractive mappings fulfilling kind of an admissibility provision in a Hausdorff \(\text{b} \)-rectangular metric space with the support of C-functions. We applied our results to establish the existence of a solution for some integralitions. Finally, an example is presented to clarify our theorem.
