Stability of Vortex Patches in Channels

Zelin Dong, Chenyun Luo

In this paper, we investigate the orbital stability of vortex patches for the two-dimensional incompressible Euler equations in both a class of domains that satisfy the ``weak fini…

Compressible Gravity-Capillary Water Waves with Vorticity: Local Well-Posedness, Incompressible and Zero-Surface-Tension Limits

Chenyun Luo, Junyan Zhang

We consider the 3D compressible isentropic Euler equations describing the motion of a liquid in an unbounded initial domain with a moving boundary and a fixed flat bottom at finite…

On a Class of Global Solutions to 3D Free-Boundary Relativistic Euler Equations with a Physical Vacuum Boundary

Marcelo M. Disconzi, Zhongtian Hu, Chenyun Luo

We consider the free-boundary relativistic Euler equations in Minkowski spacetime equipped with a physical vacuum boundary, which models the motion of a relativi…

Local Well-Posedness of the Motion of Inviscid Liquid Crystals with a Free Surface Boundary

Chenyun Luo, Hang Yu

In this article, we prove the local well-posedness of the free-boundary Lin-Liu equations describing the motion of inviscid nematic liquid crystals in the presence of surface tensi…

Small scale creation for 2D free boundary Euler equations with surface tension

Zhongtian Hu, Chenyun Luo, Yao Yao

In this paper, we study the 2D free boundary incompressible Euler equations with surface tension, where the fluid domain is periodic in , and has finite depth. We construct in…
