Periodic Solutions to the Steady Viscous Burgers Equation: A Constructive Example

Quansen Jiu, Yuhan Cao

In this paper, we consider the periodic problem to steady viscous Burgers equation with an periodic and external force. Our main aim is to construct periodic solutions to this mode…

Non-uniform Continuity for the MHD equations with only Magnetic Diffusion

Quansen Jiu, Yaowei Xie

In this paper, we prove the non-uniform continuity of the data-to-solution map for the incompressible magnetohydrodynamic (MHD) equations with only magnetic diffusion in Sobolev sp…

On Liouiville Type Theorem for the 3D Isentropic Navier-Stokes System without D-condition

Quansen Jiu, Jie Tan, Zhihong Yan

In this paper, we establish Liouville-type theorems for the steady compressible Navier-Stokes system. Assuming a smooth solution \(u \in L^p(\mathbb{R}^3)\), \(3 \le p \le \frac{9}…

Local well-posedness of strong solutions to the 2D nonhomogeneous primitive equations with density-dependent viscosity

Quansen Jiu, Lin Ma, Fengchao Wang

In this paper, we consider the initial-boundary value problem of the nonhomogeneous primitive equations with density-dependent viscosity. Local well-posedness of strong solutions i…
