摘要

In this paper, we study the existence of solutions and boundary solutions to U=f(A_11(u,v),...,A_1m1(u,v),B_11(v,u),...,B_1n2(v,u)) V=g(A_21(u,v),...,A_2m2(u,v),B_21(v,u),...,B_2n2(v,u)) We do not assume any topological structure or algebraic structure on the partial; ordering sets. The quasi-order completeness of the ranges on A_kik, B_kjk (ik=1,2,…mk, jk= 1,2,…nk) is the main condition in the theorems. We discuss the quasi-order complete sets in some concrete spaces. As corollaries, we obtain some new coupled fixed point results for mixed monotone operators. Lastly, the conclusions are applied to a system of functional equations arising in dynamic programming.
