Abstract :
The aim of this paper is to establish some fixed point theorems for $alpha$-admissible Mizoguchi-Takahashi contractive mappings defined on a ${b}$-metric space which generalize the results of Gordji and Ramezani cite{Roshan6}. As a result, we obtain some coupled fixed point theorems which generalize the results of ʹ{C}iriʹ{c} {et al.} cite{Ciric3}. We also present an application in order to illustrate the effectiveness of our results.
