We are looking for

A mathematician working in the area of mathematical general relativity and/or geometric analysis, preferably with some affinity for theoretical physics. This position will broaden the scope of the Mathematical Physics group, which has traditionally specialised in quantum (field) theory, operator algebras and non-commutative geometry, foundations of physics, and Lie theory and integrable systems, but has recently appointed an assistant professor of mathematical relativity. This new position will also strengthen IMAPP’s increasing focus on gravity as a key research theme (ranging from its mathematical language and underpinning to the theoretical study of classical and quantum gravity to the imaging of black holes by the Event Horizon Telescope), as well as the Mathematics Department’s focus on applied analysis, and geometry and topology. Women are especially encouraged to apply.

We ask

  • You have a PhD in Mathematics and are a proven independent researcher in the area mentioned above, in which yo​_u pursue your own well-defined research programme.
  • You have clear international visibility through a demonstrated track record in publishing conference appearances.
  • You have demonstrable passion for both research and teaching, excellent teaching skills, and preferably some academic teaching experience.
  • You should be able to teach a broad range of courses in our teaching programme.
  • If you are not sufficiently fluent in Dutch yet, you will initially be allowed to teach in English; however, you should be willing and able to acquire the skills necessary to lecture in Dutch within three years (Dutch language level B2).
  • You have the potential and interest to generate external research funding to support research projects.

We are

The Mathematics Department at Radboud University is part of the Institute for Mathematics, Astrophysics, and Particle Physics (IMAPP) in the Faculty of Science.

Noncommutative Calculus and the Spectral Action


Monday, 5 August 2019 – 9:00am to Friday, 9 August 2019 – 5:00pm


Room 4082, Red Centre Building, Kensington Campus, UNSW Sydney

The purpose of this workshop is to link mathematicians working in operator theory and noncommutative calculus with mathematical physicists in the area of the spectral action principle.

The Spectral Action is a new and high profile theory that unites quantum and classical action principles in a mathematically elegant construction. Professor Walter van Suijlekom (the Institute for Mathematics, Astrophysics and Particle Physics of the Radboud University Nijmegen) will give a mini-lecture series on the spectral actions during the mornings of the workshop. Talks on the spectral action will be given by other international experts, including Professor Giovanni Landi and Professor Bruno Iochum. Specific mathematical topics are trace class aysmptotic expansions, noncommutative Taylor series expansions, Dixmier trace and higher order residues.

Lecture series on “Noncommutative Geometry and Particle Physics” by Radboud Excellence Professor Chamseddine, Nijmegen

This is to announce a series of lectures delivered by Ali Chamseddine (American University of Beirut, Lebanon), who is visiting Radboud University Nijmegen this Spring as a Radboud Excellence Professor. All talks will take place in the Huygensgebouw (Science Faculty) of Radboud University Nijmegen.

The first lecture (on March 26, 2019, 15:30-16:30, HG00.622) will be intended for a broad audience (with some background/interest in physics), and will be on the noncommutative geometry underlying the Standard Model of Particle Physics. Afterwards there will be a reception.

In the second and third lecture (on April 2 and 9, 2019, 15:30-16:30 in HG00.622 and HG00.108, resp.) the formalism will be further laid out; these lectures will be more specialized. Below you find more detailed titles and abstracts.



The titles of the three lectures are:
1- Noncommutative Geometry and Particle Physics: Introduction (March 26, 2019, 15:30-16:30 in HG00.622, drinks afterwards)
2- Noncommutative Geometry and Particle Physics: Unification (April 2, 2019, 15:30-16:30 in HG00.622)
3- Mimetic Gravity and Dark Matter (April 9, 2019, 15:30-16:30 in HG00.108)

Abstract (Lecture 1)
The fundamental particles and their interactions are well represented by the the Standard Model of
Particle Physics and Einstein gravity. It is not known or understood the reasons why nature made this
choice for the particles and their representations. In this lecture, following down to top approach, I will
show that noncommutative geometry, as defined by Alain Connes, is the underlying geometry of space-time
and provides the answer to “Why the Standard Model”.

Abstract (Lecture 2)
Addressing the mathematical question of characterizing four-dimensional spin manifolds leads to a
relation similar to Heisenberg noncommutativity of coordinates and momenta in Quantum Mechanics.
I show that this relation implies the quantization of the volume of space-time and leads uniquely to
identify the underlying geometry, which turns out to be noncommutative. The resulting dynamical theory
unifies all interactions including gravity with the Standard Model the effective symmetry at low energies.

Abstract (Lecture 3)
Over the years many attempts were made to isolate the scale factor in General Relativity (known as
the dilaton) but these, however, proved not to be useful. A novel idea is presented where the scale
factor is isolated in a covariant way where it will be traded for a scalar field representing the time coordinate.
I will show that this innocent looking modification has drastic consequences on cosmology. In particular, geometric
invariants of the scalar field now mimic dark matter without the need for new interactions. These can also provide
mechanisms to avoid singularities for Friedman and Kasner cosmologies, as well as black hole singularities of
Schwarzschild like metrics.


Masterclass on Subfactors and Quantum Groups, Copenhagen

Subfactors and Quantum Groups: a combinatorial approach to some problems in Operator Algebras

Masterclass, University of Copenhagen, 29 April –  3 May 2019

The celebrated theory of subfactors studied by V. Jones in the early 1980’s finds a connection with discrete quantum groups (duals of compact quantum groups in the sense of Woronowicz) through the concept of rigid C*-tensor category thanks to works of S. Popa in the 1990’s. The aim of this 5-days masterclass is to provide a comprehensive introduction to the subfactor theory as well as the combinatorics behind in order to understand this connection and highlight some recent applications.

The masterclass will consist of three lecture series by Michael Brannan, Amaury Freslon and Stefaan Vaes, accompained by several problem sessions. Besides, there will be three contributed talks which will complement the topics treated in the mini-courses.
