Abstract
In the manuscript, using C-class function, a concept of a mixed monotone mapping is acquainted and a coupled fixed point theorems is substantiated for such nonlinear shrinkage mappings in partially ordered exact rectangular metric spaces. We enlarge and universalize the conclusions of [9].
Keywords: Rectangular quasi metric spaces, coupled fixed point; hausdorff spaces, partially ordered set, mixed monotone mapping
