Error Estimates of an Exponential Wave Integrator for the Nonlinear Schrödinger Equation with Singular Potential

Abstract. In this paper we analyze a first-order exponential wave integrator (EWI) for the nonlinear Schrödinger equation (NLSE) with a singular potential that is locally in [Formula: see text], which might be locally unbounded. A typical example is the inverse power potential su...
