一类非自治系统的小扰动

The Small Perturbation from a Kind of Nonautonomous System

本文在文[1]的基础上继续研究从 Kolmogorov 系统的常数解求它的扰动系统的周期解问题,在几种不同情况下解决了周期解的存在性、稳定性及解的近似表示式.

This paper studies how to derive a periodic solution of perturbedKolmogorov system from a constant solution of unperturbed system onthe basis of Paper[1].The existence stability and approximate expressionsof the solution are discussed in some cases.
