Published in 2019 at "Mathematical Methods in the Applied Sciences"

DOI: 10.1002/mma.5818

Abstract: We study the regularity criterion for the Navier‐Stokes equations and show that the (β1,β2,β3)‐Hölder continuity assumption in (x1,x2,x3) on the direction of the vorticity ensures the regularity of the solution. This may be viewed as… read more here.
