A minimum dissipation principle for the Rayleigh-Taylor problem in viscous magnetohydrodynamics

A variational principle for magnetohydrodynamic gravitational modes, including isotropic viscosity and the shear of magnetic field lines, is given. It is shown to imply a minimum dissipation requirement for the modes. A sufficient condition for stability given in the literature for the case of ordin...
