Coupled common fixed point theorems for four mixed weakly monotone mappings with twice power type φ-contraction condition

Abstract

By using the compatibility condition and mixed weakly monotone property, in this manuscript, we prove some coupled common fixed point theorems for four mappings with twice power type φ-contraction condition in partially ordered complete metric spaces.Our results are generalizations of the main results of Gordji, Akbartabar and Cho and Ramezani et al.
