DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSGA/85/">Re
 pulsive Curves and Surfaces</a>\nby Henrik Schumacher (Chemnitz University
  of Technology) as part of Online Seminar "Geometric Analysis"\n\n\nAbstra
 ct\nRepulsive Curves and Surfaces\n\nI am going to report on recent work o
 n the numerical optimization of tangent-point energies of curves and surfa
 ces. After a motivation and brief introduction to the central computationa
 l tools (construction of suitable Riemannian metrics on the space of embed
 ded manifolds\, a polyhedral discretization of the energies\, and fast mul
 tipole techniques)\, I am going to show a couple of numerical results. Not
  much about the shape of minimizers has been know so far. So\, for the fir
 st time\, we will be able to admire the beauty of the energies' minimizers
  and gradient flows.\n\nThis is based on joint work with Philipp Reiter (C
 hemnitz University of Technology) and Caleb Brakensiek\, Keenan Crane\, an
 d Chris Yu (Carnegie Mellon University\, Pittsburgh).\n
