On weak (measure-valued)-strong uniqueness for compressible Navier-Stokes system with non-monotone pressure law

In this paper our goal is to define a renormalised dissipative measure–valued (rDMV) solution of compressible Navier–Stokes system for fluids with non-monotone pressure–density relation. We prove existence of rDMV solutions and establish a suitable relative energy inequality. Moreover we obtain the Weak (Measure-valued)-Strong uniqueness property of this rDMV solution with the help of relative energy inequality.
