| Abstract: | By using the continuation theorem of coincidence degree theory, the existence of positive periodic solutions for a kind of nonautonomous competitive system with infinite delay and diffusion is studied. The sufficient conditions are obtained for the existence of positive periodic solutions of the system. |
