Abstract

The aim of this paper is to prove the existence of common coupled coincidence points and common coupled xed points for a pair of compatible maps satisfying condition (B) with a rational expression in partially ordered metric spaces. Further, we discuss the importance of rational expression in condition (B). Our results extend and improve the results of Luong and Thuan[16], generalize the results of Lakshmikanthamand Ciric[17] and Saud and Abdullah [2].
