摘要
研究一类带三个正平衡点的三次Kolmogorov捕食系统,并逐一研究了每个正平衡点的性态.对于具有多个正平衡点的Kolmogorov捕食系统的研究结论是少的,我们的工作是有趣的.
In this paper,a class of cubic Kolmogorov system with three positive equilibrium points are considered and each posi- tive equilibrium point is investigated on its quality. The results about Kolmogorov model with several positive equilibrium points are less seen in published references. Our research is interesting.
