Existence of Periodic Solutions for a Kind of Second Order High Dimensional Neutral Differential Systems
摘要/Abstract
摘要：
利用重合度理论研究一类二阶高维中立型泛函微分系统[x(t)+Cx(t-τ)]″+g(t,x(t-σ(t)))=p(t)的周期解的存在性,得到了几个周期解存在的充分性定理,推广了已有工作中相应的结论.
Abstract：
By using the coincidence degree theory, periodic solutions for the second order n-dimensional neutral differential systems [x(t)+Cx(t-τ)]″+g(t,x(t-σ(t)))=p(t) are studied. Some sufficient conditions are obtained. The corresponding results already known are improved and extanded.
