  Abstract

By using the composite methods, two local conservative schemes, i.e., the local energy conservative scheme and the local momentum conservative scheme are proposed to solve the fourth-order Schr?dinger equation with cubic nonlinear term. The schemes can preserve the discrete charge conservation law. And the stabilities of the schemes are analyzed by the linearization method. Finally, the correctness of the theoretical results is demonstrated by the numerical examples.
