摘要/Abstract

摘要： 考虑人体免疫缺陷病毒(HIV)传播的动力学模型, 利用流行性传染病区域的人群传播规律, 提出一类HIV传播的动力学系统. 先利用泛函同伦映射方法, 得到一类HIV传播动力学非线性系统近似解的序列及其一致收敛性, 并举例得到各次近似解, 再对HIV传播动力学系统的解进行定量和定性分析. 结果表明, 利用近似解的表示式可调节感染者人数和易感者人数的分布.

Abstract: We considered a class of dynamic model of human immunodeficiency virus (HIV) transmission and proposed a class of HIV transmission dynamic system by using the rule of population transmission in epidemic contagion region. Firstly, using the functional homotopic mapping method, we obtained the sequence of approximate solutions of a class of HIV nonlinear transmission dynamic system and their uniformly convergence, and gave an example to get all the approximate solutions. Then the quantitative and qualitative analysis of the solution for HIV transmission dynamic system was carried out. The results show that the expressions of approximate solution can regulate the distribution for the number of infected persons and susceptible persons.

Key words: approximate solution, human groups for HIV transmission, nonlinear dynamic model, homotopic mapping
