摘要
利用Krasnoselskii不动点定理,获得了一类离散m点边值问题存在至少一个正解的充分性条件,对已有文献中的一些结果进行了改进.
By using the Krasnoselskii fixed-point theorem,some sufficient conditions under which a class of discrete m-point boundary value problem has at least one positive solution were obtained.The results improved those in known literatures.
