Global dynamics of a SEI epidemic model with immigration and generalized nonlinear incidence functional

Global dynamics of a SEI epidemic model with immigration and generalized nonlinear incidence functional

In this paper, the global dynamics of an SEIepidemic model with constant immigration and general nonlinear incidence function is investigated. It is shown that there is neither a disease free equilibrium nor a basic reproduction number for this kind of models containing immigration terms. Moreover,...
