Also\nbased on that similarity\, one would expect the\nconstructi on to work equally well classically and quantum mechanically.\nWhile that is true for superfluids and solids\,\none instead finds that for genuine f luids things are made more\ncomplicated by the unusual dynamics of their t ransverse\nmodes\, which are not described by a Fock space. Focussing on the\nincompressible limit in 2+1 dimensions\, I illustrate how a consisten t\nquantum mechanical description of a perfect fluid can be obtained by\nu sing the known equivalence between the area preserving diffeomorfism \ngr oup in 2D and $SU(N)$ with $N\\to \\infty$.\n LOCATION:https://researchseminars.org/talk/CCTP_HEP/45/ END:VEVENT END:VCALENDAR
