In this work we develop a study of positive periodic solutions for a mathematical model of the dynamics of computer virus propagation. We propose a generalized compartment model of SEIR-KS type. since we consider that the population is partitioned in five classes: susceptible (S); exposed (E); infected (I); recovered (R); and kill signals (K). and assume that the rates of virus propag... https://parisnaturalfoodes.shop/product-category/flor-essence-cream/
