Coupled common fixed point theorems for mixed weakly monotone mappings in partially ordered metric spaces

摘要

In this paper, we introduce the concept of a mixed weakly monotone pair of mappings and prove some coupled common fixed point theorems for a contractive-type mappings with the mixed weakly monotone property in partially ordered metric spaces. Our results are generalizations of the main results of Bhaskar and Lakshmikantham and Kadelburg et al. Mathematics Subject Classification 2000: 54H25.
