Abstract

We study a Lie splitting scheme for a nonlinear Schrödinger-type equation with random dispersion. The main result is an approximation of the local error. Then we can deduce sharp order estimates, for instance in the case of a white noise dispersion.

Keywords

splitting schemes, nonlinear Schrödinger-type equations, stochastic partial differential equations
