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 May 6, 2022) for all scientists at the Max Planck Institute for Mathematics

Posted in

During the pandemic, regulations are imposed by different sources. The German government imposes the overall rules, but the governments of the individual Länder (federal states in Germany) as well as some cities have the freedom to impose regulations with regard to the particular situation of the area. Here we try to summarize the information relevant for our guests as best as possible and to keep it up to date. We assume no liability for this information and refer to the government websites for the official regulations:

NRW website (only in German), Federal Foreign Office's website, city of Bonn's website.

Regulations from us and the Max Planck Society

  • Lecture hall: starting April 25, 2022 there is no more 2G-rule in the lecture hall. If more than 20 people are in the lecture hall - mask obligation; if there are up to 20 people in the lecture hall - mask can be removed when sitting in one of the marked seats. There is no mask obligation for the speaker during the talk. You are welcome to participate remotely if offered for the respective talk. For conferences the mask and entry regulations are decided individually depending on the planned scale of the event.
  • Access to the institute: starting March 22, 2022 no 3G-regulation for access to the institue for contract holders and scholarship holders anymore. External people need a proof of vaccination, recovery or a daily covid test result (3G) to enter the institute.
  • The mask obligation in the institute remains, except for in your office (if the distance to other people can be maintained), while sitting in a designated seat in the lecture hall and during meals (only as long as it is necessary for consuming the meal). Medical mask , FFP2 mask or equivalent to FFP2 are accepted.

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

Die, 2022-07-05 (All day) - Don, 2022-07-14 (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. 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

Die, 2022-02-15 16:00 - Mit, 2022-03-23 15:30

Starting February 15, Don Zagier will give a lecture course entitled "Standard and less standard asymptotic methods". This course will be given in collaboration with the IGAP (Institute of Geometry and Physics, a new joint venture between SISSA and ICTP in Trieste).

The course will be streamed from Trieste twice a week (Tu/Th 4-5:30 for the first four weeks and Mo/We 2-3:30 for the last two weeks).
