摘要：
We study the existence and asymptotic behavior of positive periodic solutions of diffusive Hassell-Varley type predator-prey systems with time periodic and spatially dependent coefficients. The fixed point index theory is used to obtain necessary and sufficient conditions for the existence of positive time periodic solution. Finally, we extend the existence results to the associated elliptic models.
