| Abstract: | In this paper,some definitions of the mixed monotonicity for set-valued operators in semiordered set are introduced and relation of monotonicities are discussed.And using some properties of the total-ordered subset in semiordered set,the coupled fixed points theorems and minimax coupled fixed points theorems for mixed monotone set-valued operators are proved. |
