Existence of Positive Periodic Solutions for Neutral Liénard Equations with a Singularity of Repulsive Type
摘要
Abstract
By using Mawhin's continuation theorem, the problem of periodic solutions is studied for neutral Liénard equation with a singularity of repulsive type. Under the strong singularity condition, a new result on the existence of positive periodic solutions is obtained. It's interesting that is that the singularity at infinity is allowed indefinite type, which generalizes the corresponding results in known literature.关键词
