Fixed points of mixed non-monotone tripled operators in ordered Banach spaces and applications

This paper is concerned with a class of mixed non-monotone tripled operators under the general conditions of ordering relations in ordered Banach spaces. By means of the cone theory and technique of equivalent norms, the existence and uniqueness of xed points for such tripled operators are established. The proof method in this paper is di erent from those used in the former relevant theorems. At last, an application is presented to illustrate our result. We extend some previous existing results.
