摘要
研究一类2种群都具有扩散的捕食-被捕食系统年龄阶段结构模型.首先通过构造Lyapunov泛函证明了惟一正平衡态的局部渐近稳定性,再利用方程组的比较原理给出正平衡态全局渐近稳定的充分条件.
A two-species species have dispersal. following, by using the the positive equilibrium predator-prey stage structure model with dispersal is investigated. Both of the two It is shown that the unique positive equilibrium is asymptotic stability. In the comparison theorem, the sufficient conditions for the global asymptotic stability of are obtained.
