In this paper, we consider the permanence of a discrete SIRS epidemic model with time delays. This model is constructed from the discretization by the Euler method. Applying the technique to prove the existence of an eventual lower bound in a continuous epidemic model, a sufficient condition for the

This paper discusses a two species discrete model of mutualism with delays and feedback controls. Sufficient conditions are obtained for the permanence of the system. The results show that feedback control variables have no influence on the persistence property of the system.
## Abstract In this paper, we consider a facultative mutualism system with different delays. Sufficient criteria for permanence and global attractivity for the system are established. Ultimate uniform boundedness of the solutions ensures permanence. For the global attractivity of the system, magnit
## a b s t r a c t A nonautonomous discrete single-species system with delays and feedback control is studied. New sufficient conditions for ensuring the permanence of the system are obtained. A very important fact is found in our results, that is, that the feedback control is harmless to the perm
