摘要
在时标理论和拓扑度理论基础之上,通过应用重合度理论的连续定理和一些时标上积分不等式技巧,给出了时标上一类具有相互干扰的非自治捕食者-食饵系统周期解存在性的充分条件.
Based on the theory of the time scales and topological degree theory, by using the continuation theorem of coincidence degree theory and some skills of integral inequalities on time scales, the sufficient condition of the existence of periodic solutions for a non - autonomous predator - prey system with mutual interference on time scales is obtained.
