Global Stability of Discrete SIR Epidemic Model with A General Incidence Rate and Delay
Global Stability of Discrete SIR Epidemic Model with A General Incidence Rate and Delay

胡素娟;孙福芹;

摘要(Abstract):

This paper we study a general discrete SIR epidemic model which is derived from SIR model with distributed delay and general nonlinear incidence by using a variation of the backward Euler method.Applying a Lyapunov functional technique,it is shown that the global dynamics of each discrete SIR model is fully determined by a single threshold parameter.
