DESCRIPTION:Speakers: Cornelia Drutu\n\nIn this talk\, I shall explain the
  existence\, in non-positively curved spaces\, of a 2-dimensional isoperim
 etric gap\, similar to the one in dimension 1\, i.e. for the filling of lo
 ops by discs. The argument is based on the thinness of a particular type o
 f tetrahedra\, the minimal tetrahedra. This is joint work with Urs Lang\, 
 Panos Papasoglu and Stephan Stadler.\n\nhttps://math-events.uni-bonn.de/ev
