Coupled fixed point results for (ψ,ϕ)(ψ,ϕ)-weakly contractive mappings in ordered GG-metric spaces

In this paper, we establish coupled coincidence and common coupled fixed point theorems for (ψ,ϕ)(ψ,ϕ)-weakly contractive mappings in ordered GG-metric spaces. Presented theorems extend, generalize and improve many existing results in the literature. An example is given.
