Products of Compartmental Models in Epidemiology. [PDF]
, 2017 We show that many structured epidemic models may be described using a straightforward product structure in this paper. Such products, derived from products of directed graphs, may represent useful refinements including geographic and demographic ...

Extinction and recurrence of multi-group SEIR epidemic [PDF]
, 2013 In this paper, we consider a class of multi-group SEIR epidemic models with stochastic perturbations. By the method of stochastic Lyapunov functions, we study their asymptotic behavior in terms of the intensity of the stochastic perturbations and the ...
