Abstract
We study regularity criteria for the d-dimensional incompressible Navier-Stokes equations. We prove in this paper that if \({u \in L_\infty^tL_{d}^x((0,T)\times \mathbb{R}^d)}\) is a Leray-Hopf weak solution, then u is smooth and unique in \({(0, T)\times \mathbb{R}^d}\) . This generalizes a result by Escauriaza, Seregin and Šverák [5]. Additionally, we show that if T = ∞ then u goes to zero as t goes to infinity.
