摘要
Any weak solution u to the Navier-Stokes equations is showed to be regular under the assumption that ||u||(Lw2(0,T;L infinity(R3))) is sufficiently small, which is a limiting case of the regularity criteria derived by Kim and Kozono. Our result gives a positive answer to the question proposed by Kim and Kozono. For the incompressible magnetohydrodynamic equations, we also show the regularity of weak solution only under the assumption that ||u||(Lw2(0,T;L infinity(R3))) is sufficiently small.
