SUMMARY:Seminar Analysis: Katarzyna Mazowiecka (University of Freiburg & Un
 iversity of Warsaw)
DESCRIPTION:We investigate a fractional notion of gradient and divergence o
 perator. We generalize the div-curl estimate by Coifman-Lions-Meyer-Semmes
  to fractional div-curl quantities. We demonstrate how these quantities ap
 pear naturally in nonlocal geometric equations\, which can be used to obta
 in a regularity theory for fractional harmonic maps and critical systems w
 ith nonlocal antisymmetric potential.\\r\\nThis is a joint work with Armin
  Schikorra
