摘要 利用Banach空间中Krasnoselskii锥不动点定理,主要讨论了一类二阶周期边值问题正解的存在性,在一定意义上简化了判断此类周期边值问题正解存在性的条件,从而推广了该类问题的结果. By using a fixed point theorem of Krasnoselskii on Cone in Banach space, the existence of positive solutions of periodic boundary value problem for a class of Second-order differential equations is discussed in this paper. The established results, to some extent, simplify the sufficient conditions for the existence of positive solutions and thus generalize a conclusion for the related periodic boundary value problem.
