„Coadjoint orbits relevant to ideal fluid dynamics“
François Gay-Balmaz, Ecole normale supérieure, Paris

We explore coadjoint orbits of the group of volume preserving diffeomorphisms that are modeled on nonlinear Grassmannians of submanifolds of codimension one. These coadjoint orbits are associated to classes of singular solutions of the Euler equation of an ideal fluid. We focus on vortex loops in 2D (collections of point vortices) and on vortex sheets in 3D (collections of vortex filaments). We also determine a Feynman-Onsager condition for their prequantization. This is a joint work with Cornelia Vizman.
