Box 35195-363, Semnan, Iran Samaneh Ghods Department of Mathematics, Islamic Azad University, Semnan Branch, Semnan, Iran Journal Article 2014 12 08 In this paper, we prove some coupled coincidence point theorems for mappings with the mixed monotone property and obtain the uniqueness of this coincidence point. Then we providing useful examples in Nash equilibrium.
