Variational Iteration Method for Volterra Functional Integrodifferential Equations with Vanishing Linear Delays

Abstract

Application process of variational iteration method is presented in order to solve the Volterra functional integrodifferential equations which have multi terms and vanishing delays where the delay function $\theta (t)$ vanishes inside the integral limits such that $\theta (t)=qt$ for , $t\ge \mathrm{0}$. Either the approximate solutions that are converging to the exact solutions or the exact solutions of three test problems are obtained by using this presented process. The numerical solutions and the absolute errors are shown in figures and tables.
