| Abstract: | In this paper, We investigate two species competition system with diffusion and time dclay and functional response and impulsive effect. By using the method coincidence degree theorem, Sufficient conditions are obtained for the existence of positive periodic solutions. Moreover, some known results improved and generalized. |
| Keywords: | Impulsive effect Positive periodic solution Competition diffusive system Coincidence degree theory |
