Permanence for a Delayed Nonautonomous SIR Epidemic Model with Density-Dependent Birth Rate

Based on some well-known SIR models, a revised nonautonomous SIR epidemic model with distributed delay and density-dependent birth rate was considered. Applying some classical analysis techniques for ordinary differential equations and the method proposed by Wang (2002), the threshold value for the...
