Exact Solutions of Nonlinear Differential-difference Equations by He's Homotopy Perturbation Method

摘要

A new scheme, deduced from He's homotopy perturbation method, is presented for solving nonlinear differential-difference equations. A simple but typical example is given to illustrate the validity and great potential of He's homotopy perturbation method in solving nonlinear differential-difference equation. The results reveal that the method is very effective and simple.
