| Abstract: | A two species discrete mutualism system with time delay and feedback controls is studied in this paper. By using the difference inequality theory and constructing the suitable Lyapunov functional, we show that the system is permanent and globally attractive. Further, by applying almost periodic functional hull theory, we obtain a set of sufficient conditions which guarantee the existence of a unique global attractive positive almost periodic sequence solution of the system. |
