关于不连续分段微分系统的周期解

On the periodic solutions of discontinuous piecewise differential systems

Jaume Llibre, Douglas Duarte Novaes

摘要:

受来自应用科学不同领域的问题的启发,我们研究了以下微分系统$$x'(t)=F_0(t,x)+\varepsilon F_1(t,x)+\varepsilon^2 R(t,x,\varepsilon),$$的周期解,当$F_0$,$F_1$和$R$是不连续分段函数,且$\varepsilon$是小参数时.假设未扰动系统$x'=F_0(t,x)$的所有周期解的流形$\mathbb{Z}$的维数为$n$或小于$n$。平均理论是解决这个问题的最佳工具之一。当$F_0$、$F_1$和$R$为连续函数时,以及当$F_0=0$为一类不连续微分系统时,这一理论得到了完整的发展.然而,当$F_0\neq0$时,还没有研究间断微分系统周期解的平均理论。在本文中,我们发展了这一理论的一大类不连续微分系统。

英文摘要:

Motivated by problems coming from different areas of the applied science we study the periodic solutions of the following differential system $$x'(t)=F_0(t,x)+\varepsilon F_1(t,x)+\varepsilon^2 R(t,x,\varepsilon),$$ when $F_0$, $F_1$, and $R$ are discontinuous piecewise functions, and $\varepsilon$ is a small parameter. It is assumed that the manifold $\mathbb{Z}$ of all periodic solutions of the unperturbed system $x'=F_0(t,x)$ has dimension $n$ or smaller then $n$. The averaging theory is one of the best tools to attack this problem. This theory is completely developed when $F_0$, $F_1$ and $R$ are continuous functions, and also when $F_0=0$ for a class of discontinuous differential systems. Nevertheless does not exist the averaging theory for studying the periodic solutions of discontinuous differential system when $F_0\neq0$. In this paper we develop this theory for a big class of discontinuous differential systems.
