Abstract:
In this paper, a three species diffusive predator-prey model with functional response is studied, where all parameters are time dependent. By using the continuation theorem of coincidence degree theory, the existence of a positive periodic solution for this system is established.
Keywords:diffusive model  functional nesponse  positive periodic solution  continuation theorem of coincidence degree  fopological degree
