Melnikov analysis for planar piecewise linear vector fields with algebraic switching curve $y^n-x^m=0$

Cintia C. Santos, Oscar A. R. Cespedes

摘要:

本文研究了一类平面分段线性微分系统的极限环的最大个数$H(m,n)$,其中两个区域由曲线$y^n-x^m=0$分隔,其中$n,m$为正整数.更准确地说,我们提供了一个较低的估计$ H(m,n)$。利用Chebyshev系统的一些正精度结果和Melnikov理论,对所有的$m,n\in \mathbb{N}$,对线性中心的分段线性扰动

英文摘要:

This paper is devoted to the study of the maximum number of limit cycles, $H(m,n)$, of a planar piecewise linear differential system with two zones separated by the curve $y^n-x^m=0$, with $n,m$ being positive integers. More precisely, we provide a lower estimate of $ H(m,n)$. for all $m,n\in \mathbb{N}$, for piecewise linear perturbations of the linear center using some recent results about Chebyshev systems with positive accuracy and Melnikov Theory
