Abstract:

Regularity criteria of Leray-Hopf weak solutions to the three-dimensional  Navier-Stokes equations  in some critical spaces such as  Lorentz space, Morrey space and multiplier space are derived in terms of two partial derivatives, 1u1, ∂2u2, of  velocity fields.

Key words: Regularity criteria, Navier-Stokes equations
