摘要：
We investigate the Lie and the Strang splitting for the cubic nonlinear Schrodinger equation on the full space and on the torus in up to three spatial dimensions. We prove that the Strang splitting converges in L-2 with order 1+theta for initial values in H2+2 theta with theta is an element of (0,1) and that the Lie splitting converges with order one for initial values in H-2.
