研究了一类具有时滞的基于比率型三种群捕食者.食饵系统,给出了系统持续生存的条件.通过构造Lyapunov函数的方法得到了该系统正平衡态局部渐近稳定的充分条件.
A three-species ratio-dependent predator-prey model with time delays is investigated, conditions are given for persistence of the system. By constructing a suitable Lyapunov function, sufficient conditions are derived for the local asymptotic stability of the positive equlibrium of the system.
