摘要
本文利用整体反函数理论,研究了半线性周期边值问题,给出存在唯一性的充分条件,推广和改进了现有的结果.
In this paper, we use global inverse function theorems to investigate periodic boundary value problem of semilinear equation, and give out a sufficient condition of existense and uniqueness for periodic solution, The results generalize and improve some known results.
