-contraction and asymptotic stability of Cahn--Hilliard fronts

Bongsuk Kwon, Wanyong Shim

We study the stability of transition fronts for the one-dimensional Cahn--Hilliard equation. More precisely, we prove that for any Hölder initial datum sufficiently close to a fro…

Asymptotic self-similar blow-up for the regularized Saint-Venant equations

Yunjoo Kim, Bongsuk Kwon, Wanyong Shim

We investigate singularity formation in the regularized Saint--Venant (rSV) equations, a conservative, non-dispersive shallow water system that is formally regarded as a Hamiltonia…

Spectral stability of shock profiles for the Navier-Stokes-Poisson system

Wanyong Shim

We investigate the spectral stability of small-amplitude shock profiles for the one-dimensional isothermal Navier-Stokes-Poisson system, which describes ion dynamics in a collision…

Asymptotic stability of composite waves of shock profile and rarefaction for the Navier-Stokes-Poisson system

Wanyong Shim

We study the stability of composite waves consisting of a shock profile and a rarefaction wave for the one-dimensional isothermal Navier--Stokes--Poisson (NSP) system, which descri…

Long-Time Behavior towards Shock Profiles for the Navier-Stokes-Poisson System

Moon-Jin Kang, Bongsuk Kwon, Wanyong Shim

We study the stability of shock profiles in one spatial dimension for the isothermal Navier-Stokes-Poisson (NSP) system, which describes the dynamics of ions in a collision-dominat…
