Fixed Points for Triangular α−Admissible Geraghty Contraction Type Mappings in Partial b-Metric Spaces

In this paper, we introduce the notion of generalized C−class functions for Geraghty contraction type mappings on a set X. We utilize our new notion to prove fixed point results in the setting of triangular weak α−admissible mappings with respect to η in Partial b-Metric Spaces. Our results modify and improve many exciting results in the literature. Also, we introduce an example and an application to show the validity of our main result.
