Rational contractions and coupled fixed points (Q1716139)

From the introduction: It is our aim to propose an analytic perspective for the study of Meir-Keeler contractions over quasi-ordered metric spaces. As an application of the obtained facts, a rational type coupled fixed point theorem over quasi-ordered metric spaces is established, which includes a recent statement obtained (via rather different methods) by \textit{H. K. Nashine} and \textit{Z. Kadelburg} [Nonlinear Funct. Anal. Appl. 17, No. 4, 471--489 (2012; Zbl 1295.54071)]. \par For the entire collection, see [Zbl 1402.47001].
