On the convergence of a linear two-step finite element method for the nonlinear Schrödinger equation
ESAIM: Modélisation mathématique et analyse numérique, Tome 35 (2001) no. 3, pp. 389-405.

We discretize the nonlinear Schrödinger equation, with Dirichlet boundary conditions, by a linearly implicit two-step finite element method which conserves the L 2 norm. We prove optimal order a priori error estimates in the L 2 and H 1 norms, under mild mesh conditions for two and three space dimensions.
