Description

It is shown that the generalization of the Navier-Stokes equations to a theory with $N$ ``internal state" copies of the velocity fields is a step in a wrong direction: the $N\to\infty$ limit has no physical sense and produces wrong results, whereas the treatment of the first order terms in $1/N$ is even more complicated than the initial problem of description of turbulence in the frame of the Navier-Stokes equation.
