摘要
研究非自治多种群时滞Kolmogorov系统,给出了该系统中种群持续和灭绝的充分条件,并把得到的结果应用于非自治时滞Lotka-Volterra系统.把相关文献的有关结果推广到时滞系统.
A nonautonomous multi-species Kolmogorov system with delay is considered in this paper. Sufficient conditions are given for persistence and extinction of species in this system, and our results are applied to nonantonomous Lotka-Volterra systems with delay. It is shown that the results of R. Redheffer[-J. Math. Biol,2000,40,295-3203 are generalized to the delay systems.
