| Abstract: | In this paper,we consider the Lotka-Volterra predator-prey model with dispersal and time delay.The existence of positive periodic solution is proved,and sufficient conditions are obtained to ensure the existence of positive periodic solution. |
| Keywords: | Model of time delay and diffusion Positive periodic solution Coincidence degree |
