abstract = {<p style="text-align: justify;">In this paper, the global momentum conservation laws and the global momentum evolution laws are presented for the two-dimensional stochastic nonlinear Schrödinger equation with multiplicative noise and the two-dimensional stochastic Klein-Gordon
equation with additive noise, respectively. In order to preserve the global momenta or
their changing trends in numerical simulation, the schemes are constructed by using a
stochastic multi-symplectic formulation. It is shown that under periodic boundary conditions, the schemes have discrete global momentum conservation laws or the discrete
global momentum evolution laws. Numerical experiments confirm global momentum-preserving properties of the schemes and their mean square convergence in the time
direction.</p>},
