关于分段线性动力系统的理论

Towards Theory of Piecewise Linear Dynamical Systems

Valery A. Gaiko, Wim T. van Horssen

摘要:

本文考虑一个平面动力系统,其分段线性函数包含任意数量(但有限)的下降段,并逼近某个连续的非线性函数。通过研究其极限环的所有可能的局部和全局分支,证明了具有$k$下降段和$2k+1$奇点的分段线性动力系统至多可以有$k+2$极限环,其中的$k+1$逐个包围焦点,最后的第$(k+2)$个极限环包围系统的所有奇点.

英文摘要:

In this paper, we consider a planar dynamical system with a piecewise linear function containing an arbitrary number (but finite) of dropping sections and approximating some continuous nonlinear function. Studying all possible local and global bifurcations of its limit cycles, we prove that such a piecewise linear dynamical system with $k$ dropping sections and $2k+1$ singular points can have at most $k+2$ limit cycles, $k+1$ of which surround the foci one by one and the last, $(k+2)$-th, limit cycle surrounds all of the singular points of this system.
