【摘要】 研究一个不含负反馈的时滞非自治三物种的“食饵-捕食者”Lotka-Volterra系统,旨在证明,在适当条件下,此系统是一致持续的,通过构造一个合适的Lyapunov泛函方程组,我们可以证明此系统的全局稳定性。更多还原

【Abstract】 A delayed nonautonomous three-species predator-prey Lotka-Volterra system without dominating instantaneous negative feedback is investigated. It is proved that the system is uniformly persistent under appropriate conditions. By constructing a suitable Lyapunov functional, sufficient conditions are derived for the glabal stability of system.更多还原
