Series Solutions Using Variational Iteration, Differential Transform and Adomian Decomposition Methods.

Abstract

In this research work, a proposed Lassa fever model is solved by the Differential transform method (DTM), Variational Iteration Method (VIM) and Adomian decomposition methods (ADM). Prior to approximate solutions to the Epidemiology model, region of positive-invariant was examined. Results showthat, the Variational Iterative Method converges faster than the two other methods.
