摘要
运用比较定理结合构造Lyapunov泛函的方法,讨论了一类纯时滞非自治扩散的Lotka-Volterra生态系统的持续生存和全局吸引性,补充完善了相关结果.
Permanence and globally asymptotic stability of a nonautonomous Lotka-Volterra system with delays and dispersion are discussed by means of a suitable Lyapunove functional,some new results are obtained.These results are supplemented.
