Abstract
This paper is concerned with the blowup criterion for mild solution to the incompressible Navier–Stokes equation in higher spatial dimensions . By establishing an regularity criterion in the spirit of [11], we show that if the mild solution u with initial data in , becomes singular at a finite time , then
The corresponding result in 3D case has been obtained in [24]. As a by-product, we also prove a regularity criterion for the Leray–Hopf solution in the critical Besov space, which generalizes the results in [17], where blowup criterion in critical Lebesgue space is addressed.
