摘要
构造具有三个极限环 (其中两个稳定 )的三次Kolmogorov系统。这个例子肯定地回答了Coleman(1982 )提出的一个问题。在多项式处理中 。
A cubic Kolmogorov prey-predator system is constructed and is shown to have three small amplitude limit cycles, among which two are stable. This can serve as an affirmative answer to a question proposed by Coleman (1982). The computer algebraic system, Maple, is applied to manipulate polynomials in dealing with the system.
