摘要 研究了一类多时滞的离散捕食系统,运用差分方程的比较原理,得到了保证系统种群持续生存的充分条件,并对定理条件可实现性进行了实例数值验证. A discrete predator-prey system with several delays is studied.By applying the comparison theorem of difference equation,the sufficient conditions are obtained for the permanence of the system.Meanwhile,we give a suitable example for supporting our theoretical result.
