具有脉冲的时滞微分方程的周期解

Periodic Solutions of Delay Differential Equations with Impulses

将小时滞Yoshizawa型周期解定理推广到脉冲时滞微分方程 ,并应用它得到了含脉冲的一类非线性扰动系统的周期解存在的充分条件 .

For a class of impusive differential equation with delay the authors spread the Yoshizawa's theory about periodic solutions. By it a sufficient condition is gained for the existence of periodic solutions of the system with nonlinear perturb.
