摘要
通过构造格林函数,借助Banach空间中不连续增算子的不动点定理,研究了一类Banach空间中二阶微分方程周期边值问题解的存在性.
On the basis of the construct of Green＇s functions and the fixed point theorem for increasing operators without continuity, we are concerned with the existence of solutions for second order periodic boundary value problem in Banach spaces.
