Abstract
If $mu$ is a probability measure on the set of suitable weak solutions of the 3D Navier-Stokes equations, invariant for the time-shift, with finite mean dissipation rate, then at every time t the set of singular points is empty $mu$-a.s. The existence of a measure $mu$ with the previous properties is also proved; it may describe a turbulent asymptotic regime.File in questo prodotto:
