关于HIV传输的SICA模型

On SICA models for HIV transmission

Cristiana J. Silva, Delfim F. M. Torres

摘要:

研究了均匀混合种群中不同种群规模下人类免疫缺陷病毒(HIV)传播动力学的SICA(Susceptible-Infectious-Chronic-AIDS)数学模型。我们考虑由常微分方程系统给出的SICA模型和由分数阶和随机微分算子系统给出的一些推广。局部和全局稳定性的结果证明了确定性,分数,和随机型SICA模型。两个案例研究,在佛得角和摩洛哥,进行了调查。

英文摘要:

We revisit the SICA (Susceptible-Infectious-Chronic-AIDS) mathematical model for transmission dynamics of the human immunodeficiency virus (HIV) with varying population size in a homogeneously mixing population. We consider SICA models given by systems of ordinary differential equations and some generalizations given by systems with fractional and stochastic differential operators. Local and global stability results are proved for deterministic, fractional, and stochastic-type SICA models. Two case studies, in Cape Verde and Morocco, are investigated.
