The blow-up criterion for the compressible Navier-Stokes equations

Chao Wang (Paris 7)

We prove a blow-up criterion in terms of the upper bound of the density for the strong solution to the 3-D compressible Navier-Stokes equations. The initial vacuum is allowed. The main ingredient of the proof is a priori estimate for an important quantity under the assumption that the density is upper bounded, whose divergence can be viewed as the e ffective viscous flux.
