Convergence of Variational Iteration Method for Second-Order Delay Differential Equations

[摘要] This paper employs the variational iteration methodto obtain analytical solutions of second-order delay differential equations. The corresponding convergence results are obtained, and an effective technique for choosing a reasonable Lagrange multiplier is designed in the solving process. Moreover, some illustrative examples are given to show the efficiency of this method.
