摘要

摘要我们考虑了一个具有不连续延迟中性反馈的微分方程。在相空间中，我们描述了取决于若干参数的初始函数类。我们证明，在一定时间内，解会返回到一个类似的类，可能带有其他参数。通过对参数变化的分析，可以描述周期性解及其稳定性。我们证明存在无限多的稳定周期解。

Periodic solutions of a differential equation with a discontinuous delayed neutral-type feedback

We consider a differential equation with a discontinuous delayed neutral-type feedback. In the phase space, we describe classes of initial functions that depend on a number of parameters. We show that in a certain time, solutions return to an analogous class, possibly with other parameters. The analysis of the change in the parameters allows describing periodic solutions and their stability. We show that infinitely many of stable periodic solutions exist.
