A review of recent applications of the relative entropy method to discontinuous solutions of conservation laws

A Vasseur - Quarterly of Applied Mathematics, 2023 - ams.org
Dafermos [Arch. Rational Mech. Anal. 70 (1979), pp. 167–179] proved the weak/strong
principle for conservation laws. It states that Lipschitz solutions to conservation laws …

Stability of Hill's spherical vortex

K Choi - Communications on Pure and Applied Mathematics, 2024 - Wiley Online Library
We study stability of a spherical vortex introduced by M. Hill in 1894, which is an explicit
solution of the three‐dimensional incompressible Euler equations. The flow is axi‐symmetric …

Long-time behavior towards viscous-dispersive shock for Navier-Stokes equations of Korteweg type

S Han, MJ Kang, J Kim, H Lee - Journal of Differential Equations, 2025 - Elsevier
We consider the so-called Naiver-Stokes-Korteweg (NSK) equations for the dynamics of
compressible barotropic viscous fluids with internal capillarity. We handle the time …

Contraction property for large perturbations of shocks of the barotropic Navier–Stokes system

MJ Kang, AF Vasseur - Journal of the European Mathematical Society, 2020 - ems.press
This paper is dedicated to the construction of a pseudo-norm for which small shockprofiles of
the barotropic Navier–Stokes equations have a contraction property. This contraction …

Contraction for large perturbations of traveling waves in a hyperbolic–parabolic system arising from a chemotaxis model

K Choi, MJ Kang, YS Kwon… - Mathematical Models and …, 2020 - World Scientific
We consider a hyperbolic–parabolic system arising from a chemotaxis model in tumor
angiogenesis, which is described by a Keller–Segel equation with singular sensitivity. It is …

Uniqueness and Weak-BV Stability for Conservation Laws

G Chen, SG Krupa, AF Vasseur - Archive for Rational Mechanics and …, 2022 - Springer
Let a 1-d system of hyperbolic conservation laws, with two unknowns, be endowed with a
convex entropy. We consider the family of small BV functions which are global solutions of …

Well-posedness of the Riemann problem with two shocks for the isentropic Euler system in a class of vanishing physical viscosity limits

MJ Kang, AF Vasseur - Journal of Differential Equations, 2022 - Elsevier
We consider the Riemann problem composed of two shocks for the 1D Euler system. We
show that the Riemann solution with two shocks is stable and unique in the class of weak …
