摘要: 用泛函的方法研究一类二阶微分方程周期解的存在性. 构造一Hilbert空间H, 其中的元素是具有周期性的连续函数. 再由这类方程的特点 构造H→H的算子, 将求周期解问题转化为求算子方程问题. 由方程的特点该算子 是同胚, 算子方程有解, 从而该二阶微分方程有周期解.

关键词: 二阶微分方程, 周期解, 算子方程, 微分同胚

Abstract: We studied a class of two order differential equation s by means of the functional method. We constructed a Hilbert space H in wh ich the element is continuous function and a operator T: H→H. Then we c an turn the existence of periodic solution of this class of equations into the s olvability of a operator equation.

Key words: two order differential equation, periodic solution, operator equation, differential homeomorphism
