Description
In this talk, I will discuss touching dipoles (Sadovskii vortices) in the 2D Euler flows, which are traveling wave solutions whose vorticity support remains in contact with a symmetry axis.
I will explain how a family of touching dipoles arises as maximizers of the kinetic energy under natural constraints. This family includes classical examples such as the Chaplygin-Lamb dipole and Sadovskii vortex patch as particular cases.
