Query: On the application of homotopy--perturbation and Adomian decomposition
  methods to the linear and nonlinear Schr\"{o}dinger equations   I discuss a recent application of homotopy perturbation and Adomian
decomposition methods to the linear and nonlinear Schr\"odinger equations. I
propose a generalization of the procedure for the treatment of a wider class of
problems.
