In (2008), Zhang proved the existence of fixed points of mixed monotone operators along with certain convexity and concavity conditions. In this paper, mixed monotone single-valued and multi-valued operators of Meir-Keeler type are defined and two fixed point theorems are proved. Our results, extend the results of Zhang.
