摘 要:
The relative entropy functional has been widely used in the analysis of weak-strong uniqueness for the compressible Navier-Stokes system, meaning that a weak solution coincides with the strong solution on the lifespan of the latter. In this talk we discuss its application in numerical analysis:
1) convergence of a suitable numerical approximation;
2) convergence rate of the numerical approximation.
