We explore the existence of a fixed point as well as the uniqueness of a mapping in an ordered b-metric space using a generalized (ψˇ,ηˆ)-weak contraction. In addition, some results are posed on a coincidence point and a coupled coincidence point of two mappings under the same contraction condition. These findings generalize and build on a few recent studies in the literature. At the end, we provided some examples to back up our findings.
