In this paper, a numerical solution of population dynamics of human immunodeficiency type
1 virus (HIV-1) model is considered by using Legendre spectral-collocation method. The …

In this research work, we study the Human Immunodeficiency Virus (HIV) infection on helper
T cells governed by a mathematical model consisting of a system of three first-order …

In this paper, the Pseudospectral Legendre (PL) method is presented to approximate the
solution of the HIV infection model of CD4< sup>+ T cells. The method is based on the …

In this article, numerical techniques have been developed to solve a system of two nonlinear
integro-differential equations which arises in biological model. This model has been solved …

In this work, the mathematical model is considered on COVID-19 which makes the lives of
people in the world into a hell. This present model has four components that are expressed …

The spectral collocation method has gained great interest for many researchers in the last
decade due to the rapid development in obtaining the optimal solution for real phenomena …

In this paper, the quasilinearization and Lagrangian methods are used for solving a model of
the HIV infection of CD4^++ T cells. This approach is based on the Lagrangian method by …

Numerical analysis is the area of mathematics that creates, analyzes, and implements
algorithms for solving numerically the problems from real-world applications of algebra …

Malaria is a possibly dangerous infection brought about by a parasite. This infection is more
normal in nations with heat and humidities. Because of chromosomal changes, the elements …
