Fourier integrator for periodic NLS: low regularity estimates via discrete Bourgain spaces

Alexander Ostermann, Frédéric Rousset, Katharina Schratz

In this paper, we propose a new scheme for the integration of the periodic nonlinear Schrödinger equation and rigorously prove convergence rates at low regularity. The new integrat…
