摘要
研究一类"食物有限"基于比率的Holling-Tanner离散捕食者-食饵模型.利用差分方程的不等式理论及振动理论,证明在一定条件下,该系统是持久的.
In this paper, a "food-limited" discrete ratio-dependent Holling-Tanner predator-prey model is stud- ied. By using the theory of difference inequality and the oscillation theory of difference equation, it is showed that the system is permanence under some conditions
