DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDEq/159/">A
  Lax representation\, symmetries\, and conservation laws for the three-dim
 ensional Euler-Helmholtz equations</a>\nby Oleg Morozov as part of Geometr
 y of differential equations seminar\n\nLecture held in room 303 of the Ind
 ependent University of Moscow.\n\nAbstract\nI will consider the three-dime
 nsional Euler-Helmholtz equations for an inviscid incompressible fluid and
  reformulate them in a vorticity-type form by introducing a vector potenti
 al. I will exhibit a Lax representation with a non-removable parameter for
  the resulting system. I will discuss local symmetries and conservation la
 ws of the system. Using the Lax representation\, I will derive a shadow of
  a cosymmetry and find nonlocal conservation laws via the construction of 
 the canonical conservation law on the Whitney sum of the tangent and cotan
 gent coverings. Finally\, I will present a Bäcklund transformation betwee
 n the tangent and cotangent coverings and describe its action on local sym
 metries and local cosymmetries.\n
