Abstract

In this manuscript, using rational type contractive conditions the existence and uniqueness of common $n$-tupled fixed point for a pair of mappings in complete $b$-metric spaces are studied. Using the derived results some fixed theorems can be deduced in $b-$metric spaces.

Summary

Introduction and preliminaries

The Bananch contraction theorem is the most important technique for solving nonlinear integral equations, differential equations and functional equations etc. Paknazar et al [14] introduced the concept of a new g-monotone mapping and defined the notions of n-fixed point and n-coincidence point and proved some related theorems for nonlinear contractive mappings in partially ordered complete metric spaces. In [22] the authors introduced the notion of compatibility for n-tupled coincidence points and proved n-tupled fixed point for compatible mappings satisfying contractive type conditions in partially ordered metric spaces. Husain et al [23] present some n-tupled coincidence point results for a pair of mappings without mixed monotone property satisfying a rational type contractive condition in metric spaces equipped with a partial ordering as well as present results on the existence and uniqueness of n-tupled common fixed points.
