Abstract.
We study the interior regularity of weak solutions of the incompressible Navier-Stokes equations in Ω×(0,T), where and 0<T<∞. The local boundedness of a weak solution u is proved under the assumption that is sufficiently small for some (r,s) with and 3≤r<∞. Our result extends the well-known criteria of Serrin (1962), Struwe (1988) and Takahashi (1990) to the weak space-time spaces.
