Almost Periodic Solution of Two Species Predator-Prey System with Stage-Structure and Double Density Restrict

This paper considers a kind of nonautonomous system of two species predator-prey system with double density restrict and stage-structure for prey. The sufficient conditions are obtained for guaranteeing the permanence of the system by Laypunov method. Then the existence and uniqueness of the positive almost periodic solutions for almost periodic systems are also discussed. Some new results obtained.
