In this short note we prove the existence of fixed points for nondecreasing mappings in ordered b-metric spaces. Our results improve the recent results, established by F. Zabihi and A. Razani [Fixed point theorems for hybrid rational Geraghty contractive mappings in ordered b-metric spaces, Journal of Applied Mathematics, Volume 2014, Article ID 929821, 9 pages], with much more general conditions and shorter proofs. An example is given to show the superiority of our generalization.openAccesshttps://creativecommons.org/licenses/by-nc-nd/4.0/article10.5937/KgJMath1502183K2-s2.0-84951191287
