摘要: 应用Schauder不动点定理和傅氏分析技术, 推广了二阶时滞微分方程周期解的结果, 证明了2k阶非线性时滞微分方程在L2(0,2π)空间中2π周期解的存在性与惟一性. 保证结果成立的条件是通常Lazer型非共振条件的自然推广.

关键词: 2k阶时滞微分方程, 周期解, Schauder不动点定理

Abstract: Applying Schauder fixedpoint theorem and Fourier’s method, we generalized the results on theexistence and uniqueness of the periodic solutions for a class of second order delay differential equations, and gave the existence and uniqueness of 2πperiodic solutions for (2k)thorder nonlinear delay differential equations on space L2(0,2π). The condition to ensure the theorems is a variety of usual Lazer type one.

Key words: (2k)thorder delay differential equation, periodic solution, Schauder fixedpoint theorem
