Support growth of vorticity for bi-rotational Euler flows in high dimensions

In-Jee Jeong, Deokwoo Lim

We study incompressible Euler equations in $R^{d}$ with $d \geq 4$ under bi-rotational symmetry without swirl, which reduces the Euler equations to a scalar vorticity advecti…

On the optimal rate of vortex stretching for axisymmetric Euler flows without swirl

Deokwoo Lim, In-Jee Jeong

For axisymmetric flows without swirl and compactly supported initial vorticity, we prove the upper bound of $t^{4/3}$ for the growth of the vorticity maximum, which was conjectured…

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

Kyudong Choi, Deokwoo Lim

We consider the incompressible Euler equations in $R^{2}$ when the initial vorticity is bounded, radially symmetric and non-increasing in the radial direction. Such a radial distribu…
