SUMMARY:Helicity in dispersive continuum mechanics - Sergey Gavrilyuk (Aix
  Marseille Université)
DTSTART:20221214T153000Z
DTEND:20221214T163000Z
UID:TALK193366@talks.cam.ac.uk
DESCRIPTION:New conservation laws are obtained for the equations of disper
 sive continuum mechanics describing Euler&ndash\;van der Waals&ndash\;Kort
 eweg&rsquo\;s fluids\, fluids containing small gas bubbles\, and long&ndas
 h\;free surface gravity waves (Serre&ndash\;Green&ndash\;Naghdi equations)
 . In particular\, analogs of helicity invariants are found. This is a join
 t paper with Henri Gouin
