 \n \n\nTitle: Geodesics\, vortex sheets\, and generalized fluid flows\n\n \
 n\nAbstract: \n\n \n\nWe discuss ramifications of Arnold’s group-theoretic 
 approach to ideal hydrodynamics as the geodesic flow for a right-invariant 
 metric on the group of volume-preserving diffeomorphisms. It turns out that
  many equations of mathematical physics\, such as the motion of vortex shee
 ts or fluids with moving boundary\, have Lie groupoid\, rather than Lie gro
 up\, symmetries. We present their geodesic setting\, which also allows one 
 to describe multiphase fluids\, homogenized vortex sheets and Brenier’s gen
 eralized flows. This is a joint work with Anton Izosimov.
