A priori error analysis of linear and nonlinear periodic Schrödinger equations with analytic potentials
This paper is concerned with the numerical analysis of linear and nonlinear Schrödinger equations with analytic potentials. While the regularity of the potential (and the source term when there is one) automatically conveys to the solution in the linear cases, this is no longer true in general in the nonlinear case. We also study the rate of convergence of the planewave (Fourier) discretization method for computing numerical approximations of the solution.
