On some recent fixed point results for (psi, phi)-contractive mappings in ordered partial b-metric spaces

Abstract: In this paper we unite, complement, improve, and generalize the recent fixed point results in ordered partial b-metric spaces, established by Mustafa et al. [Z. Mustafa, J. R. Roshan, V. Parvaneh, Z. Kadelburg, J. Inequal. Appl., 2013 (2013), 26 pages], with much shorter proofs. An example is given to show the superiority of the results obtained.
