Abstract:
A delayed periodic Lotka-Volterra type predator-prey model with prey dispersal in two-patch environments is investigated.A sufficient condition of the existence of positive periodic solution is established for the system by using Gaines and Mawhin's continuation theorem of coincidence degree theory.
Keywords:predator-prey diffusive system  positive periodic solution  coincidence degree theory
