Abstract
By means of the continuation theorem based on coincidence degree theory and homotopy mapping, the existence of positive periodic solution of a predator-prey system with stage-structured and cannibalism for prey is obtained. The phenomenon is revealed that when the cannibalism rate of adult prey species and the arrest rate of adult prey species are enough small, the system will bring periodic oscillation of biological nature.关键词
