Desingularization of time-periodic vortex motion in bounded domains via KAM tools

Zineb Hassainia, Taoufik Hmidi, Emeric Roulley

We examine the Euler equations within a simply-connected bounded domain. The dynamics of a single point vortex are governed by a Hamiltonian system, with most of its energy levels…

Rigorous derivation of the leapfrogging motion for planar Euler equations

Zineb Hassainia, Taoufik Hmidi, Nader Masmoudi

The main goal of this paper is to explore the leapfrogging phenomenon in the inviscid planar flows. We show for 2d Euler equations that under suitable constraints, four concentrate…
