周期时间制约的非Hamliton可积Kolmogorov系统的混沌与次谐波

Chaos and Subharmonic Bifurcations in the Periodic Time-dependent Non-Hamiltonian Kolmogorov System

本文研究一类非Hamilton可积的Kolmogorov生态系统的周期激励模型，应用Melnikov方法，得到了该系统存在混沌与次谐分枝的某些充分条件。

This paper is devoted to show that exlstence of subharmonic bifurcations and chaotic behavior in the periodic time-dependent non-Hamiltonian Kolmogorov System by using the Melnikov's method．
