%0 Journal Article %T Regularity of weak solutions to the magneto-hydrodynamics equations in terms of the direction of velocity %A Yuwen Luo %J Electronic Journal of Differential Equations %D 2009 %I Texas State University %X In this article, we study the regularity of weak solutions to the 3D incompressible magneto-hydrodynamics equations. We obtain a new class of regularity criteria in terms of the direction of the velocity. Our result extend some results known for incompressible Navier-Stokes equations. %K Magneto-hydrodynamics equation %K regularity %K Serrin criteria %U http://ejde.math.txstate.edu/Volumes/2009/132/abstr.html
