Workshop on Operator Algebras and Applications: Non-Commutative Geometry, December 4 - 8, 2023, The Fields Institute

This workshop will explore current themes in noncommutative geometry, including topics that lie at the interfaces of noncommutative geometry with Riemannian geometry, sub-Riemannian geometry, mathematical physics, random matrix theory, representation theory, cyclic homology, number theory and arithmetic geometry. The workshop will feature Alain Connes' series of 3 Coxeter Lectures with the title From rings of operators to noncommutative geometry, as well as a minicourse of 3 lectures by Eckhard Meinrenken on Symplectic geometry of the moduli space of hyperbolic 0-metrics. In addition to plenary talks, time will be reserved early in the week for contributions from graduate students and other beginning researchers.

Some funding has been set aside to provide (modest) travel grants to young researchers who wish to participate in the meeting. Those seeking such funding should contact the organizers as soon as possible.

MPI Homage


The Max Planck Institute held this week a special event that officially closed down Manin's Seminar, after its continued existence since 1969, first in Moscow and then in Bonn. The event hosted a brief overview by Misha Kapranov on the history of the seminar, followed by two lectures, one by Don Zagier and one by myself. The videos of the lectures are available at this link:

Hybrid Workshop on Noncommutative Geometry, Free Probability Theory and Random Matrix Theory, June 13 - 17, 2022, University of Western Ontario

This hybrid workshop is supported by the Fields Institute.  All talks will be broadcast online. To gain access to the talks, please register free of charge here

Workshop description: Topological recursion is a method for counting maps of a certain topology using only planar maps. The theory arose from work in 2D quantum gravity and the discovery that matrix integrals are related to maps on surfaces. These matrix integrals also appear in models of quantum gravity on noncommutative spaces and  in quantum field theories  on these spaces. The same matrix integrals arise in free probability and recent work has shown a surprising connection between higher order free  independence and maps on surfaces of positive genus.

This workshop will bring together a group of researchers working in noncommutative geometry (NCG), free probability theory (FPT) and random matrix theory (RMT) to foster collaboration in an emerging area of research that is at the intersection of these three fields.

Mini courses 

  1. Gaetan Borot (Humboldt University, Berlin): Asymptotics of matrix integrals and topological recursion.
  1. James Mingo (Queens, Canada): Free independence of random variables
  1. Raimar Wulkenhaar (Muenster, Germany): How topological recursion organises quantum fields on noncommutative geometries

This conference will be in hybrid format. All talks will be broadcast on zoom. To access the talks please register free of charge using the link provided above.
