Vs. Beskin et Iv. Kuznetsova, CONTINUITY OF MAGNETOHYDRODYNAMIC FLOWS NEAR SINGULAR POINTS, Journal of experimental and theoretical physics, 86(3), 1998, pp. 421-428
The continuity of hydrodynamic and magnetohydrodynamic axisymmetric st
ationary flows near singular points of acoustic surfaces is investigat
ed when the flows are far from spherical symmetry. It is shown that th
e flow is still continuous at the time the characteristics undergo a b
ifurcation, but may become discontinuous when the flow is distorted fu
