Oscillatory approximations and maximum entropy principle for the Euler system of gas dynamics
Eduard Feireisl, Mária LukáÄová-Medvid'ová, Changsheng Yu
We show that the measure-valued solutions of the Euler system of gas dynamics generated by oscillatory sequences of consistent approximations violate the principle of maximal entro…

On admissible solutions to the coupled Riemann problem with heat-flux discontinuity
Changsheng Yu, Tiegang Liu
We study the Riemann problem for the compressible Euler equations with a stationary coupling interface across which a discontinuity in the heat flux is prescribed. This coupling gi…
