Regularity of solutions to the Navier-Stokes equation. (English) Zbl 0923.35117

The authors are concerned with obtaining a sufficient condition for the global continuation of strong solutions of the 3D Navier-Stokes equation. They prove that it is sufficient to control only two components of the vorticity vector, or the gradients of the two components of the velocity vector.
