Regularity of Leray-Hopf solutions to Navier-Stokes equations   (I)-Critical interior regularity in weak spaces
  We consider the interior regularity of Leray-Hopf solutions to Navier-Stokes equations on critical case L^2_w(0,T;L^\infty(R^3)). Particularly, an open problem proposed in [KK] was solved.
