Streszczenie
We consider the compressible Navier–Stokes–Korteweg (N-S-K) equations. Through a remarkable identity, we reveal a relationship between the quantum hydrodynamic system and capillary fluids. Using some interesting inequalities from quantum fluids theory, we prove the stability of weak solutions for the N-S-K equations in the periodic domain $\varOmega =\mathbb {T}^{N}$, when $N=2,3$.
