摘要:

该文讨论一类具有Beddington-DeAngelis响应函数的阶段结构捕食模型.利用Routh-Hurwitz判别定理讨论了其正常数平衡解的局部渐近稳定性, 通过构造Lyapunov函数方法得到了全局渐近稳定性.

关键词: 捕食模型, 正常数解, 稳定性

Abstract:

This paper deals with stage-structured predator-prey systems with Beddington-DeAngelis functional response. The local asymptotical stability is given by Routh-Hurwitz criterion, and global asymptotic stability are established from Lyapunov functions.

Key words: Predator-prey Models, Positive Constant Solution, Stability
