• solitary wave solution

We extend the homotopy analysis method to solving the discrete modified KdV equation The bright soliton solution expressed by a series of exponential functions is obtained, which agrees well with the exact solution. It indicates the validity and great potential of the homotopy analysis method in solving complicated nonlinear problems.
