DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSGA/107/">R
 igidity of $\\epsilon$-harmonic maps of low degree</a>\nby Jasmin Hörter 
 (Karlsruhe Institut of Technology) as part of Online Seminar "Geometric An
 alysis"\n\n\nAbstract\nIn 1981 Sacks and Uhlenbeck introduced their famous
  alpha-approximation of the Dirichlet energy for maps from surfaces and sh
 owed that critical points converge (away from finitely many points) to a h
 armonic map. Now one can ask whether every harmonic map is captured by thi
 s limiting process. Lamm\, Malchiodi and Micallef answered this for maps f
 rom the two sphere into the two sphere and showed that the Sacks-Uhlenbeck
  method produces only constant maps and rotations if the energy lies below
  a certain threshold. We investigate the same question for the epsilon-app
 roximation of the Dirichlet energy.\nJoint work with Tobias Lamm and Mario
  Micallef.\n
