Abstract

The paper examines a numerical show of a human T-cell lymphotropic infection sort I HTLV transmission of CD4+ T-cells. “The model allows for CD4+ T cell subsets of susceptible, latently infected, and actively infected cells and leukemia cells. In fact, this mathematical model in the fractional differential system form describes the interaction between susceptible CD4+ cells, latently HIV-infected cells, actively HIV-infected cells, latently HTLV-infected cells, Tax-expressing HTLV-infected cells, free HIV particles, HIV-specific Cytotoxic T lymphocytes and HTLV-specific” Cytotoxic T lymphocytes. In this paper, we analyze the human HTLV-I virus model with the help of the Lie symmetry method. The Lie group technique is an effective analytic algorithm that derives an exact solution. A Lie point symmetry of a differential system is a group of transformations that maps every solution of the system to another solution of the same system thus this method gives a set of solutions. The Lie group symmetry method has many advantages, including integrating ordinary differential equations, classifying differential equations, linearizing partial differential equations, obtaining the general solution of differential equations, obtaining conservation laws, and many others. The infinitesimal generators of the time fractional human HTLV-I virus system by the Lie method are derived in what follows. Next, the similarity reduction method is used to establish precise solutions for the invariant by using the Lie point symmetries. The intended system’s conservation laws are retrieved using Ibragimov’s approach and Noether’s theorem.
