DESCRIPTION:Title: <a href="https://researchseminars.org/talk/cam/14/">Lie
 -Poisson methods for incompressible magnetohydrodynamics on the sphere</a>
 \nby Michael Roop (Chalmers and GU) as part of CAM seminar\n\nLecture held
  in MV:L14.\n\nAbstract\nWe present a novel structure preserving numerical
  method for Lie-Poisson systems on the dual of semidirect product Lie alge
 bras. The method fully preserves the underlying geometry\, namely the Lie-
 Poisson structure and all the Casimirs\, and nearly preserves the Hamilton
 ian function. We illustrate the method on two models describing the motion
  of magnetic fluids\, the equations of incompressible magnetohydrodynamics
 \, and the Alfvén wave turbulence equations. For the latter case\, we rev
 eal the formation of large scale quasi-periodic vortex blob dynamics.\n\nT
 his is a joint work with Klas Modin.\n
