摘要
运用 Ｓｃｈａｕｄｅｒ不动点定理，在非线性项 ｆ满足超线性或次线性条件下，给出了边值问题正解的存在性结果，将微分方程的相关结果推广到了差分方程．
Using Schauder's fixed-point theorem and assuming that nonlinear term f satisfies the condition of superlinearity or sublinearity, the existence of positive solutions of following boundary value problem is concluded, so that the relevant results from differential equations can be spread to difference equations.
