DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GEOTOP-A/98/
 ">Conformal Geometry in Magnetic Relaxation</a>\nby Oliver Gross (TU Berli
 n - Germany) as part of GEOTOP-A seminar\n\n\nAbstract\nThe magnetic relax
 ation problem studies the self-organization of magnetic field lines in a p
 erfectly conducting fluid to a steady state. In this talk I will discuss s
 uch a process from the perspective of conformal geometry. A key insight is
  the conformal equivalence between force-free magnetic fields and so-calle
 d geodesible vector fields. Building on this insight\, I will discuss a co
 mputational approach to magnetic relaxation that is driven only by local g
 eometry optimization. The method is based on a structure-preserving discre
 tization for pressure-confined regions of an ideal plasma with free bounda
 ry conditions\, which is represented by a collection of thickness curves i
 nteracting with each other. \nThis is joint work with Albert Chern (UC San
  Diego\, CA\, USA)\, Ulrich Pinkall (TU Berlin\, Germany) and Peter Schrö
 der (Caltech\, Pasadena\, CA USA).\n
