HOMOTOPY PERTURBATION METHOD FOR SOLVING A MODEL FOR HIV INFECTION OF CD4 + T CELLS

In this article, homotopy perturbation method is implemented to give approximate and analytical solutions of nonlinear ordinary differential equation systems such as a model for HIV infection of CD4 + T cells. A modification of the homotopy perturbation method (HPM), based on the use of Pade´ approximants, is proposed. Some plots are presented to show the reliability and simplicity of the methods.
