摘要: 用Schauder不动点定理, 研究二阶迭代微分系统满足边界条件x(a)=y(a)=a, x(b)=y(b)=b或x(a)=y(a)=b, x(b)=y(b)=a时解的存在唯一性, 其中x[2](t)=x(x(t)).

关键词: 二阶迭代微分系统, 边值问题, 存在性, Schauder不动点定理

Abstract: By using Schauder fixed point theorem, the author study the  existence and uniqueness of solutions for second-order iterative differential system satisfying the boundary conditions x(a)=y(a)=a, x(b)=y(b)=b或x(a)=y(a)=b, x(b)=y(b)=a, where x[2](t)=x(x(t)).

Key words:  , second-order iterative differential systems, boundary value problem, existence, Schauder fixed point theorem
