Coupled Coincidence Point Results for Mappings Without Mixed Monotone Property in Partially Ordered `G`-Metric Spaces

In this paper, we prove some coupled fixed point theorems for nonlinear contractive mappings which doesnchr('39')t have the mixed monotone property, in the context of partially ordered `G`-metric spaces. Hence, these results can be applied in a much wider class of problems. Our results improve the result of D. Dorichr('39'){c}, Z. Kadelburg and S. Radenovichr('39'){c} [Appl. Math. Lett. (2012)]. We also present two examples to support these new results.
