摘要
本文考虑周期系数的三种群 Lokta-Volterra模型 ,种群间既有捕食关系又有竞争关系 ,得到其正周期解的存在性及其全局渐近稳定性的条件 。
In this paper, we consider the lotka\|volterra system for three species. There predator and competition as well in three species. A sufficient condition is obtained for existence of periodic solution and global asymptotic stability. Finally, an example is given to illustrate the feasibility of these condition.
