On Existence of Periodic Solutions for Rayleigh Equation with a Deviating Argument

研究了一类具偏差变元的Rayleigh方程:x″(t)+f(x′(t))+g(t,x(t-τ(t)))=p(t)周期解的存在性问题,得到了一些新的结果.所获结果改进和推广了已有文献中的相关结论.

Existence of periodic solutions for a kind of non-autonomous Rayleigh equation x″（t）＋f（x′（t））＋g（t,x（t-τ（t）））=p（t） is studied, and some new results are obtained. Our work generalizes and improves the known results in the literature.
