On the regularity of weak solutions to the magnetohydrodynamic equations. (English) Zbl 1072.35154
Summary: We study the regularity of the weak solution to the incompressible magnetohydrodynamic equations. We obtain some sufficient conditions for regularity of weak solutions, which are similar to that of incompressible Navier-Stokes equations. Moreover, our results demonstrate that the velocity field of the fluid plays a more dominant role than the magnetic field does on the regularity of solution to the magnetohydrodynamic equations.
