Fixed point results for weak contractions in partially ordered b-metric space

Objectives: 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 ((sic), (eta) over cap)-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. Result: In partially ordered b-metric spaces, it is discussed how to obtain a fixed point and its uniqueness of a mapping, and also investigated the existence of a coincidence point and a coupled coincidence point for two mappings that satisfying generalized weak contraction conditions.
