In this paper, we studied the dynamics of typhoid fever model; we tested for theexistence
and uniqueness of solution for the model using the Lipchitz condition to ascertain the …

We analyze with four compartments a deterministic nonlinear mathematical model of typhoid
fever transmission dynamics. Using the Lipchitz condition, we verified the existence and …

A numerical method is presented in this paper to solve fractional integro-differential
equations in the sense of Caputo, the fractional derivative is considered. The proposed …

The aim of this paper is to apply Variational Iteration Method (VIM) to solve typhoid fever
model for a given constant population. This mathematical model is described by nonlinear …

In this paper, we presents a deterministic mathematical model on the dynamics of typhoid
fever disease. The Adomian Decomposition Method (ADM) is used to solve the model …

This paper presents an analysis of PSIuIeTR type model, which are used to study the
transmission dynamics of typhoid fever diseases in a population. Basic idea of typhoid fever …

This study gears towards finding a numerical solution to fractional integro-differential
equations. The techniques involve the application of the homotopy perturbation method and …

In this paper, we present a deterministic model that captures the essential dynamics of
infectious diseases. Differential Transform Method (DTM) is applied to attempt the series …

Abstract In this work, Differential Transform Method (DTM) was employed to obtain the series
solution of the SIRV COVID-19 model in Nigeria. The validity of the DTM in solving the …
