Nonlinear stability of large amplitude viscous shock wave for compressible magnetohydrodynamics flows
Lilu Sahu, T Raja Sekhar
In this article, we establish the nonlinear time-asymptotic stability of viscous shock wave with arbitrary large amplitude to the Cauchy problem for the compressible magnetohydrody…

Supersonic sonic patch solution for the two-dimensional Euler equations with a van der Waals equation of state
Anamika Pandey, T. Raja Sekhar
We investigate supersonic transonic phenomena in the two-dimensional compressible Euler equations governed by a polytropic van der Waals equation of state. In contrast to the ideal…
