Abstract :
In this work explicit symplectic time-integration schemes for the semi-discrete Discontinuous Galerkin Method are theoretically analyzed and validated. The main results are, the finding of conserved fully discrete energies, the derivation of the corresponding stability conditions and a comparison of some simulations results for the schemes.
