带接种疫苗的年龄结构MSEIR流行病模型非负解的存在惟一性

The existence and uniqueness of nonnegative solutions of an age-structured MSEIR epidemic model with vaccination

讨论带接种疫苗的年龄结构MSEIR流行病模型.在常数人口规模的假设下,运用泛函分析中的有界线性算子半群理论和积分方程理论,证明了该模型非负解的存在惟一性.

This paper discusses an agestructured MSEIR epidemic model with an agedependent vaccination rate ψ(a).Under the assumption of constantsized population,by using the theory of C0semigroup of bounded linear operator in functional analysis and the theory of integral equation,the existence and uniqueness of nonnegative solutions of this model are proved.
