摘要
讨论了一种带年龄结构的SARS疾病模型,它是一组非线性偏微分方程组,应用有界线性算子的C0-半群理论及非线性扰动理论,证明了该方程组非负解的存在唯一性及稳定性.
A class of age-structured SARS epidemic model described by a set of partial differential equations is discussed. By means of the theory of C_0-semigroup and its nonlinear perturbation of bounded linear operators, we prove the existence and uniqueness and stability of solution for this SARS epidemic model.
