Abstract
This double-sized chapter contains two related themes that were supposed to be covered by two independent chapters of the handbook in the original project:
- (1)
weak solutions of the Navier-Stokes equations in the barotropic regime and
- (2)
weak solutions of the Navier-Stokes-Fourier system.
- (1)
Various notions of weak solutions, their relevance, and their mutual relations.
- (2)
Global existence of weak solutions.
- (3)
Notions of relative energy functional, dissipative solutions and relative energy inequality and its impact on the investigation of the stability analysis of compressible flows.
- (4)
Weak strong uniqueness principle.
- (5)
Longtime behavior of weak solutions.
For physical reasons, we shall limit ourselves to the three-dimensional physical space.
