本文研究一类带有反应扩散项、食饵具阶段结构的食饵捕食模型.通过运用Lyapunov直接法和构造合理的Lyapunov泛函,建立了系统边界平衡点和正平衡点的全局渐近稳定性,得到系统全局稳定的充分必要条件,提高已有的结论.
In this paper, we investigate a delayed reaction-diffusion model which describes a two-species predator-prey system with diffusion terms and stage structure. By using the direct Lyapunov method and constructing appropriate Lyapunov functional, we establish the global stability of the positive equilibrium of the system. Our results improve some known results on delay diffusion predator-prey system.
