| Abstract: | This paper studies a two dimensional Lotka Volterra diffusion systems with a finite number of discrete delays. Our purpose is to demonstrate that the time delays are harmless for uniform persistence of the solutions of the system. The results are obtained by monotone method for delay reaction diffusion systems. |
