Hausdorff School: "Von Neumann Algebras: Deformation/Rigidity, free Probability and Subfactors"

May 17 - 25, 2016

University of Bonn

  • May 17-21: Big lecture hall (Großer Hörsaal), Wegelerstr. 10, Bonn
  • May 23-25: Universitätsclub, Konviktstr. 9, Bonn

Organizers: Dietmar Bisch, Vaughan Jones, Sorin Popa, Dima Shlyakhtenko

Description: The Fourteenth Annual Spring Institute on Noncommutative Geometry and Operator Algebras (NCGOA) took place in Bonn, Germany, during the Hausdorff Trimester Program "Von Neumann Algebras". It was a combination of spring school and international conference. During the school part of the meeting, which coincided with the introductory school of the trimester program, several mini-courses were given by leading experts. The conference consisted of a number of invited research talks.
