摘要
针对一类具有扩散、时滞和HollingⅡ类功能反应的捕食系统模型,运用比较定理,得到系统一致持久的充分条件.利用Lyapunov稳定性理论,通过构造合适的Lyapunov函数,得到相应周期系统周期解存在唯一及全局渐近稳定的充分条件.
A predator-prey system with Holling Ⅱfunctional response,diffusion and delay is studied.The sufficient conditions for the uniform persistence of this system is discussed by using the comparison theorem.By constructing the suitable Lyapunov functions,the sufficient conditions for the global asymptotic stability of this system is obtained and discussed.
