Existence of positive periodic solution for nonautonomous predator-prey system with diffusion and time delay

[摘要] A two-species nonautonomous predator-prey system with time delay and diffusion is investigated. A sufficient condition of the existence of positive periodic solution is established for the system by using the continuation theorem of coincidence degree theory. (C) 2003 Elsevier B.V.
