Optimal regularity for all time for entropy solutions of conservation laws in
Shyam Sundar Ghoshal, Billel Guelmame, Animesh Jana +1
This paper deals with the optimal regularity for entropy solutions of conservation laws. For this purpose, we use two key ingredients: (a) fine structure of entropy solutions and (…
On blow up of solutions of isentropic Euler system
Shyam Sundar Ghoshal, Animesh Jana
In this article, we study the break-down of smooth and continuous solutions to isentropic Euler system in multi dimension. Sideris [Comm. Math. Phys. 1985] proved the blow up of sm…
Higher regularity for entropy solutions of conservation laws with geometrically constrained discontinuous flux
Shyam Sundar Ghoshal, Stephane Junca, Akash Parmar
For the Burgers equation, the entropy solution becomes instantly BV with only initial data. For conservation laws with genuinely nonlinear discontinuous flux, it is well…
Fractional regularity for conservation laws with discontinuous flux
Shyam Sundar Ghoshal, Stephane Junca, Akash Parmar
This article deals with the regularity of the entropy solutions of scalar conservation laws with discontinuous flux. It is well-known [Adimurthi et al., Comm. Pure Appl. Math. 2011…
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…
