α-psi -φ-contractive mappings in ordered partial b-metric spaces

In this paper, we introduce the concept of α-psi -φ-contractive self mapping in complete ordered partial b- metric space, and we study the existence of xed points for such mappings under some conditions. Presented theorems in this paper extend and generalize the results derived by Mustafa et al., also some examples are given to illustrate the main results.
