摘要
以捕食者有附加食物、食饵有阶段结构和避难所的时滞捕食系统为研究对象,利用迭合度理论得到了该系统存在正周期解的充分条件,并利用数值模拟验证了所得条件的正确性.
A delayed predator-prey model with additional food for predator,stage-structured and refuge for prey is studied.We employ the coincidence degree theory to obtain the sufficient conditions of the positive periodic solution.In the end,the numerical simulation is given to show the validity of the obtained conditions.
