Numerical Solution of Fractional-Order HIV Model Using Homotopy Method

الملخص EN

In this study, we construct a convergent algorithm for generating an approximate analytic solution for the fractional HIV infection of CD4+ T cells with Atangana–Baleanu fractional derivatives in the Caputo sense.

We compute the solution by utilizing the fractional homotopy analysis transform method (FHATM) and achieved a convergence region of the solution by employing an auxiliary parameter.

Moreover, we apply a numerical scheme proposed by Toufik and Atangana for solving this kind of problem and compared with our results.

A good agreement between the new algorithm and the numerical scheme is remarkable.

The solution via the present algorithm can be obtained without any linearization or discretization which makes it reliable and easy to apply.
