Abstract

In this talk, we will discuss the concentration phenomenon of the kinetic energy p|u|² ,associated to isentropic compressible Navier-Stokes equations, in ⁿ with n=2,3 and the adiabatic constant ∈[1,n/2]. Expect a space-time set with Hasusdorff dimension less than to equal to Γ (n) +1 with

Γ (n)=max{(n),n-(n/(n)+1)} and (n)=(n(n-1)-n/n-),

no concentration phenomenon occurs.
