摘要:

利用奇摄动方法研究一类HIV传播的动力学模型, 先构造模型解的外部解和内层解, 再进行匹配, 得到了模型解的合成展开式, 并对解进行了精度比较, 证实了渐近展开式具有较高的精度. 结果表明, 得到的近似解可以描述流行性传染病区域的人群传播规律.

关键词: HIV传播, 奇摄动, 渐近解

Abstract:

A class of mode for HIV propagation dynamics was studied. By means of the singular perturbation method, firstly, the outer solution and interior solution were constructed; secondly, they were matched,  obtaining composite expansions of solution for the model; finally, comparing the accuracies for the solutions verifies the asymptotic expansion possesses a better accuracy. Finded approximate solution may describe the law of HIV propagation in the crowd of epidemics region.

Key words: HIV transmission, singular perturbation, asymptotic solution
