Remarks on the blow-up of solutions for the 3-D Euler equations

Abstract

We consider a blow-up of smooth, local-in-time solutions of the 3-D incompressible Euler equations. We give a localized analogy of the Beale-Kato-Majda-type criterion that if the solution blows up in an isolated set in our sense, the blow-up is carried with the blow-up of vorticity in that set. Besides, we show that in general the blow-up process is controlled by a suitable norm of any two components of vorticity in Cartesian coordinates.
