Multi-symplectic magnetohydrodynamics: II, addendum and erratum
A recent paper arXiv:1312.4890 on multi-symplectic magnetohydrodynamics (MHD) using Clebsch variables in an Eulerian action principle with constraints is further extended. We relate a class of symplecticity conservation laws to a vorticity conservation law, and provide a corrected form of the Poincar\'e-Cartan differential form formulation of the system. We also …
