Applied mathematics and computation, 2006•ElsevierWe propose a multisymplectic scheme to solve the coupled Klein–Gordon–Schrödinger
system. The scheme preserves the multisymplectic geometry structure exactly by satisfying
the discrete multisymplectic conservation law, and can simulate the original waves well in a
long time. This scheme also has discrete quasi-norm conservation law. Numerical
experiments demonstrate the consistency between the theoretical analysis and the
numerical results.
