On a generalized time-varying SEIR epidemic model with mixed point and distributed time-varying delays and combined regular and impulsive vaccination controls

Agarwal, Ravi P.; De La Sen, Manuel; Ibeas, Asier; Alonso-Quesada, Santiago (2010-12-14)

This paper discusses a generalized time-varying SEIR propagation disease model subject to delays which potentially involves mixed regular and impulsive vaccination rules. The model takes also into account the natural ...
On the existence of equilibrium points, boundedness, oscillating behavior and positivity of a SVEIRS epidemic model under constant and impulsive vaccination

De La Sen, Manuel; Agarwal, Ravi P.; Ibeas, Asier; Alonso-Quesada, Santiago (2011-03-13)

This paper discusses the disease-free and endemic equilibrium points of a SVEIRS propagation disease model which potentially involves a regular constant vaccination. The positivity of such a model is also discussed as well ...
