Existence of BV solution for the Euler-Poisson system in one dimension with large initial data
Shyam Sundar Ghoshal, Boris Haspot, Animesh Jana
This paper deals with the existence of BV solution for the Euler-Poisson system endowed with a pressure law. More precisely, we prove the existence of weak solution in the BV f…

Weak-Strong Uniqueness for the Isentropic Euler Equations with Possible Vacuum
Shyam Sundar Ghoshal, Animesh Jana, Emil Wiedemann
We establish a weak-strong uniqueness result for the isentropic compressible Euler equations, that is: As long as a sufficiently regular solution exists, all energy-admissible weak…
