A Note on the Regularity Criterion of Weak Solutions of Navier-Stokes Equations in Lorentz Space
Keyword(s):
This paper is concerned with the regularity of Leray weak solutions to the 3D Navier-Stokes equations in Lorentz space. It is proved that the weak solution is regular if the horizontal velocity denoted byũ=(u1,u2,0)satisfiesũ(x,t)∈Lq(0,T;Lp,∞(R3)) for 2/q+3/p=1, 3<p<∞.The result is obvious and improved that of Dong and Chen (2008) on the Lebesgue space.
