| Abstract: | It studied a discrete Lotka-Volterra model with a finite number of time delays. On the basis of persistence functions and by means of qualitative analysis, the conditions for the uniform persistence and extinction of the model were obtained. The result indicated that it has the same persistence conditions as the counterpart in continuous model. |
