| Abstract: | In this paper, a predator-prey system while prey has density dependence and group defense ability was discussed .By qualitative analysis, the author obtained sufficient conditions for stability of equilibrium points and for existence of limit cycles of the system .These new results provide a reliable theoretical foundation for making further study on this class of system. |
