TAMED 3D NAVIER–STOKES EQUATION:: EXISTENCE, UNIQUENESS AND REGULARITY.

In this paper, we prove the existence and uniqueness of a smooth solution to a tamed 3D Navier–Stokes equation in the whole space. In particular, if there exists a bounded smooth solution to the classical 3D Navier–Stokes equation, then this solution satisfies our tamed equation. Moreover, using this tamed equation we can give a new construction for a suitable weak solution of the classical 3D Navier–Stokes equation introduced in Refs. 16 and 2. [ABSTRACT FROM AUTHOR]
