摘要：In this paper, a Gilpin-Ayala predator-prey model with time-dependent delay with m preys and ( n − m ) $(n-m)$ predators is studied, which can be seen as a modification of the traditional Lotka-Volterra competition predator-prey system model. Two sets of sufficient conditions on the permanence of the system are obtained. One set is delay dependent, while the other set is delay independent.
