具有星形节点和齐次非线性性的平面动力学:超越希尔伯特的第16问题
Qualitative planar dynamics with star nodes and homogeneous nonlinearities: beyond Hilbert's $16^{th}$ problem
AI总结:
本文研究了具有星形节点和齐次非线性性的平面动力学,通过分析多项式向量场的极限环问题,超越了希尔伯特第16问题的现有研究范围。
摘要:
本文对多项式平面向量场的动力学进行了全面研究,这些向量场的线性部分是单位矩阵的倍数,而非线性部分是任意次数n>1的齐次多项式。该研究扩展了其他作者之前的工作,后者主要关注极限环的存在性和数量。一般结论还应用于两类示例,其中非线性部分的次数为2和3,我们为此提供了相位图。
英文摘要:
This is a full study of the dynamics of polynomial planar vector fields whose linear part is a multiple of the identity and whose nonlinear part is a homogeneous polynomial of arbitrary degree $n>1$. It extends previous work by other authors that was mainly concerned with the existence and number of limit cycles. The general results are also applied to two classes of examples where the nonlinearities have degrees 2 and 3, for which we provide a set of phase portraits.
