关于Chouikha等时性判据
On Chouikha's isochronicity criterion
摘要:
最近A.R.Chouikha给出了方程$x"+g(x)=0$原点中心等时性的一个新的刻画,其中$g$是定义在$0 \in \R$某个邻域内的实光滑函数.我们描述了他的性格和一些新的发展主题的另一个证据。
英文摘要:
Recently A.R.Chouikha gave a new characterization of isochronicity of center at the origin for the equation $x"+g(x)=0$, where $g$ is a real smooth function defined in some neighborhood of $0 \in \R$. We describe another proof of his characterization and some new development of the subject.
