摘要 首先应用单调方法给出具有阶段结构的Lotka-Volterra竞争扩散模型整体解的存在唯一性,然后通过线性化方法和Lyapunov泛函方法证明:在弱竞争条件下该模型的正平衡点必全局渐近稳定. The global existence and uniqueness of solutions to the diffusive Lotka-Volterra competitive system with stage-structure are given by monotony method. Using linearization and Lyapunov function, the global asymptotic stability of the positive equilibrium point for this system under weak competitive is proved.
