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 [23]. As a result, we obtain some coupled fixed point theorems which generalize the results of airie et al. [6]. We also present an application in order to illustrate the effectiveness of our results.
