摘要
In this paper, several sufficient conditions are established for the persistence and extinction in a Lotka-Volterra system with time delay. Based on the use of Lyapunov functionals techniques, necessary and sufficient conditions are also given for global asymptotic stability of the positive equilibrium for autonomous systems.
