“…The present works contributes to a rigorous error analysis of full discretizations for low-dimensional nonlinear Schrödinger equations by higherorder time-splitting pseudospectral methods. For this purpose, unifying and extending techniques exploited in [15,20,22,23,28,30], we utilize an analytical framework of nonlinear evolutionary Schrödinger equations, fractional power spaces defined by the principal linear part, the formal calculus of Lie-derivatives, bounds for iterated Liecommutators, and results on the approximation error of pseudospectral methods; see also [9,11,14,17,19,27].…”
