三次Kolmogorov捕食系统的多个稳定极限环(英文)
Multiple Stable Limit Cycles for a Cubic Kolmogorov Prey-Predator System
【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 ,利用了计算机代数系统Maple
【Abstract】 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.
