摘要
讨论一类对食饵分阶段,带有比率依赖的捕食动力学系统,论述了该系统的持久生存.通过构造李雅普诺夫函数,又分别获得了正平衡点及边界平衡点的局部和全局的渐近稳定性.
This paper studies the asympototic behavior of a radiodependent predatorprey system with stage structure.It is shown that the system is permanent under some appropriate conditions.By constructing Lyapunov functions,we give some sufficient conditions under which the possible steady states are respectively local and global
