Title: Regularity of weak solutions to the magneto-hydrodynamics
       equations in terms of the direction of velocity

Author: Yuwen Luo (Chongqing Univ. of Technology, China)

Abstract:
 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.
