研究了一类具有无限时滞和年龄结构的Lotka-Volterra型生态系统的持久性,利用比较原理和对系统的右端泛函的分析,得到了种群持久生存的充分性条件.
The permanence of Lotka-Volterra type predator prey system with stage structure and infinite delay is investigated in this paper.By using of comparison theorem and analyze the right-hand functional of the system,the sufficient conditions of permanence of ecosystem is obtained.
