The Max Planck Institute for Mathematics Declares its Solidarity with the People in Ukraine

Posted in

We strongly agree with the statements of the Alliance of Science Organisations in Germany, the European Mathematical Society, and the President of the Max Planck Society.

We are in strong solidarity with our mathematical friends and colleagues in Ukraine. As a practical help, our guest program can offer a medium-term perspective for Ukrainian scientists.

Corona Virus – Relevant information (as of June 7, 2022) for all scientists at the Max Planck Institute for Mathematics

Posted in

Starting June 7, 2022, all Corona measures from MPIM are lifted.

  • wearing a mask is now voluntary in the whole institute and there is no 3G rule for external visitors anymore.
  • the limit and mask obligation for the lecture hall is also lifted.
  • However, if a member of staff asks you to wear a mask when entering their office, we kindly ask you to respect this.
  • We urgently ask you to stay home if you have any symptoms suggestive of the Corona virus and report every positive tested case to or 0228-402-255.

The recommendations remain:

  • Participate in virtual meetings and talks.
  • Wash and disinfect your hands regularly.
  • Keep at least a 1.5m distance.
  • Ventilate the rooms regularly.

Fields Medal awarded to Maryna Viazovska. Former doctoral student of the Max Planck Institute for Mathematics receives highest distinction in mathematics

Posted in

The Fields Medal is considered the Nobel Prize of mathematics. This year the International Mathematical Union chose to award it to Maryna Viazovska, who wrote her doctoral thesis at the Max Planck Institute for Mathematics with Don Zagier and received her PhD from the University of Bonn in 2013. The Ukranian mathematician is second woman to ever receive this prize.

Virtual ICM 2022. Live stream and in person talks at the Max Planck Institute for Mathematics

Posted in
Tue, 05/07/2022 (All day) - Thu, 14/07/2022 (All day)
The International Congress of Mathematicians 2022 (ICM 2022), which was originally planned for St. Petersburg, will now take place as a fully virtual event over 5–14 July 2022. In order to keep some of the spirit of the ICM, all talks will be streamed live in the MPIM lecture hall (except on the weekend). Three of the talks will be given in person at MPIM by Bernhard Schölkopf, Marc Levine, and Catharina Stroppel.

Arithmetic Groups and 3-Manifolds

Arithmetic groups provide a fruitful link between various areas, such as geometry, topology, representation theory and number theory. Methods from geometry and topology hinge on the fact that arithmetic groups are lattices in Lie groups, whereas the theory of automorphic forms establishes a connection to representation theory and number theory. This interplay is especially intriguing in the setting of hyperbolic 3-manifolds. Indeed many conjectures in 3-manifold theory tend to be much more accessible for hyperbolic 3-manifolds whose fundamental groups are arithmetic, and conversely such manifolds provide the simplest set-up in which some of the most exciting new phenomena in the Langlands program can be studied. This conference will bring together researchers with various backgrounds around links between number theory and 3-manifolds. Central topics of the conference are the cohomology of arithmetic groups, the relation between torsion and L²-torsion, profinite invariants of 3-manifolds, and number theoretic ramifications.

Limited funding to cover travel cost and accommodation is available for early carreer participants.

The conference is planned as a hybrid event.

Who can participate?
We are currently planning to run the event according to the "3G" rule, which means you have to be fully vaccinated (with a EU-recognized vaccine, at least 2 doses, last vaccination at least 14 days previously) OR recovered from Covid (positive test min. 28 days and max. 90 days old) OR tested (certified negative test result not older than 24 h (rapid antigen test) or 48 h (PCR test)). There currently is a mask obligation in the institute.
It will be announced here, in case these regulations change.

The registration is now closed.

If you have questions, please contact
