Abstract:By the theory of periodic parabolic operators, Shauder estimates and bifurcation, the existence of positive periodic solutions for periodic prey-predator model with saturation is discussed. The necessary and sufficient conditions to coexistence of periodic system are obtained.
Keywords:periodic parabolic operator  principal eigenvalue  priori estimates  bifurcation
