Multisymplectic Hamiltonian Formulation for a One-Way Seismic Wave Equation of High-order Approximation

Based on the Lagrangian density and covariant Legendre transform, we obtain the multisymplectic Hamiltonian formulation for a one-way seismic wave equation of high-order approximation. This formulation provides a new perspective for studying the one-way seismic wave equation. A multisymplectic integrator is also derived.
