Jahnke, Tobias; Lubich, Christian Error bounds for exponential operator splittings. (English) Zbl 0972.65061 BIT 40, No. 4, 735-744 (2000). The authors obtain error bounds for Strang splittings involving unbounded operators. They apply the results to a numerical method for the Schrödinger equation, in which the Laplacian is discretized by a Fourier method.
