1. Application of Adomian Decomposition Method and Variational Iteration Method to Dynamical System Problems

Babatunde Morufu Yisa

Volume 12, Issue 1 , Spring 2020, , Pages 83-90

Abstract
  Adomian decomposition method and He’s variational Iteration method are applied to nonlinear oscillator problems that involve conservative type of oscillators. The methods proved to be effective for the general and specific cases due to their algorithms that admit nonlinear terms in the problems. ...  Read More

2. Shifted Chebyshev Approach for the Solution of Delay Fredholm and Volterra Integro-Differential Equations via Perturbed Galerkin Method

Kazeem Issa; Jafar Biazar; Babatunde Morufu Yisa

Volume 11, Issue 2 , Autumn 2019, , Pages 149-159

Abstract
  The main idea proposed in this paper is the perturbed shifted Chebyshev Galerkin method for the solutions of delay Fredholm and Volterra integrodifferential equations. The application of the proposed method is also extended to the solutions of integro-differential difference equations. The method ...  Read More
