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.

Minicourse Speakers:

• Remi Boutonnet (CNRS, Université de Bordeaux) A few basics on von Neumann algebras
• Adrian Ioana (UC San Diego) Applications of asymptotic properties of group actions and II1 factors
• Masaki Izumi (University of Kyoto) An operator algebra approach to the classification of certain fusion categories
• Emily Peters (Loyola University Chicago) The classification of small-index subfactors
• Dimitri Shlyakhtenko (UC Los Angeles) Free probability and von Neumann algebras
• Stefaan Vaes (KU Leuven) II1 factors with exactly two crossed product decompositions
• Dan Voiculescu (UC Berkeley) Free probability for pairs of faces

Invited Speakers:

• Dietmar Bisch (Vanderbilt University) Singly generated planar algebras
