Tripled Common Fixed points for weak (u, Phi, Psi)- Constractions in Partially Ordered Metric Space

Abstract

In this article, we present tripled coincidence point theorems for F : X^3 ? X and g : X ?  X satisfying weak (\mu, ?, \Psi)- -contractions in partially ordered metric spaces. We also provide non-trivial examples to illustrate our results and new concepts presented herein. Our results unify, generalize and complement various known comparable results from the current literature, Berinde and Borcut [22], Abbas et. al., Aydi et al. [23] and many more previous known results.
