非自治Kolmogorov系统周期解的摄动

Perturbation from a Periodic Solution of Kolmogorov Nonautonomous System

本文从 Kolmogorov 系统的一个周期解求出了它的摄动系统的周期解,给出了该周期解存在与稳定的充分条件,并给出了解的近似表示式.

In this paper,a periodic solution of kolmogorov perturbed system isgiven by utilizing aperiodic solution of unperturbed system,some sufficentconditions on the existence and stability of this solution are derived;theapproximate expression of the solution is shown.
