Stability of vortex quadrupoles with odd-odd symmetry

Kyudong Choi, In-Jee Jeong, Yao Yao

For the 2D incompressible Euler equations, we establish global-in-time () stability of vortex quadrupoles satisfying odd symmetry with respect to both axes. Speci…

Stability and instability of Kelvin waves

Kyudong Choi, In-Jee Jeong

The -waves of Kelvin are uniformly rotating patch solutions of the 2D Euler equations with -fold rotational symmetry for . For Kelvin waves sufficiently close to the…

Infinite growth in vorticity gradient of compactly supported planar vorticity near Lamb dipole

Kyudong Choi, In-Jee Jeong

We prove linear in time filamentation for perturbations of the Lamb dipole, which is a traveling wave solution to the incompressible Euler equations in . The main ing…

Stability of radially symmetric, monotone vorticities of 2D Euler equations

Kyudong Choi, Deokwoo Lim

We consider the incompressible Euler equations in when the initial vorticity is bounded, radially symmetric and non-increasing in the radial direction. Such a radial distribu…

Growth of perimeter for vortex patches in a bulk

Kyudong Choi, In-Jee Jeong

We consider the two-dimensional incompressible Euler equations. We construct vortex patches with smooth boundary on and whose perimeter grows with time. More precisely,…

On the winding number for particle trajectories in a disk-like vortex patch of the Euler equations

Kyudong Choi, In-Jee Jeong

We consider vortex patch solutions of the incompressible Euler equations in the plane. It is shown that the winding number around the origin for most particles in the patch grows l…
