Threshold and stability results for an age-structured SEIR epidemic model
In this paper, an age-structured SEIR epidemic model is considered. The existence and uniqueness of a positive solution for this model is proved. Threshold results for the existence of endemic states are established under certain conditions. The local stability for the steady states is also examined. (C) 2001 Elsevier Science Ltd.
