Stability of Rarefaction Waves to the 1D Compressible Navier-Stokes Equations with Density-dependent Viscosity

Quansen Jiu, Yi Wang, Zhouping Xin

In this paper, we study the asymptotic stability of rarefaction waves for the compressible isentropic Navier-Stokes equations with density-dependent viscosity. First, a weak soluti…

Well-Posedness of the Limiting Equation of a Noisy Consensus Model in Opinion Dynamics

Bernard Chazelle, Quansen Jiu, Qianxiao Li +1

This paper establishes the global well-posedness of the nonlinear Fokker-Planck equation for a noisy version of the Hegselmann-Krause model. The equation captures the mean-field be…

Finite time blow-up analysis for the generalized Proudman-Johnson model

Jie Guo, Quansen Jiu

In this paper, we study the generalized Proudman-Johnson equation posed on the torus. In the critical regime where the parameter is close to and slightly greater than 1, we est…

Stability and Instability on the De Gregorio Modification of the Constantin-Lax-Majda model

Jie Guo, Quansen Jiu

The Constantin-Lax-Majda (CLM) model and the De Gregorio model which is a modification of the CLM model are well-known for their ability to emulate the behavior of the 3D Euler equ…
