Corona Virus – Relevant information (as of August 4, 2021) for all scientists at the Max Planck Institute for Mathematics

Posted in

The Corona regulations are divided into the areas in which they apply. For some aspects, there are different resolutions for NRW, the city of Bonn and the institute respectively. Please find all updates marked yellow in the respective areas.

Updated Corona Regulations (valid from August 1, 2021):

During the pandemic, regulations are imposed by different sources. The German government imposes the overall rules but the governments of the individual Länder (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 in Bonn

  • UPDATE: From Friday, July 29, 2021 persons from up to 5 households are allowed to meet without person restrictions (plus immunized persons from additional households).
  • UPDATE: From Friday, July 29, 2021 the mask requirement generally applies in public transport and in inside public areas.
  • UPDATE: From Friday, July 9, 2021 in many areas, including restaurants etc., the obligation to collect contact data may be dropped.
  • UPDATE: From Wednesday, June 16, 2021, restaurants etc. are allowed to open outside without negative test, indoor may be opened as long as the state's (NRW) incidence is also below 35 even without negative tests, a seating obligation is given and contact tracing is ensured.


You can get more information on the city of Bonn's website.

MPIM Mathematicians in Home Office. Research Continues Online

Posted in

While the members of the Max Planck Institute for Mathematics work from their home office, some seminars and research activities continue online. Please check the weekly program and the Bonn math calendar. The announcements there contain the access information. In addition, many of MPIM's researchers have set up virtual offices. Please contact the persons you would like to discuss with individually.

MPIM's library, IT services, and the administration remain open to institute members, some with reduced opening hours. Persons without MPIM access card cannot enter the institute until further notice.

Practical and administrative information for present and future visitors are on our Corona information web page.

Twinned Conference on Homotopy Theory with Applications to Arithmetic and Geometry

Twinned Conference on Homotopy Theory with Applications to Arithmetic and Geometry, June 27 - 30, 2022

The field of homotopy theory originated in the study of topological spaces up to deformation, but has since been applied effectively in several other disciplines. Indeed, homotopical ideas lead to the resolution of several long-standing open conjectures, for instance on smooth structures on spheres, the moduli of curves, and the cohomology of fields. More recently, Bhatt, Morrow, and Scholze used homotopical methods to compare different cohomology theories for algebraic varieties, thereby resolving open questions in arithmetic geometry. In a similarly arithmetic vein, Galatius and Venkatesh initiated the study of Galois representations with homotopical means, whereas Clausen and Scholze revisited the foundations of analytic topology. These and other recent developments in the interface of arithmetic and topology opened up new lines of attack towards classical open questions, which sparked a wide range of current research activities. This conference intends to survey some of the most spectacular recent advances in the fields, thereby paving the way to new developments and future interactions. Our goal is to foster scientific exchange and collaboration between established researchers, emerging leaders, early career mathematicians, and graduate students.

Lecture course by Don Zagier

Posted in

Starting May 10, Don Zagier will give a joint IGAP*/MPIM lecture course entitled “From 3-manifold invariants to number theory”, intended to be accessible to mathematicians in all fields and at all levels. The course will take place on

Mondays 4pm–6pm and Fridays 2pm–4pm,

starting on Monday, May 10, and ending on July 16. All lectures will be streamed online on Zoom, from MPIM in May and from Trieste in June and July. The course is available to everybody (including mathematicians not at the MPI, SISSA, or ICTP), but one must register in order to participate. The meeting details are given below.

Dennis Gaitsgory New Director at MPIM

Posted in

Dennis Gaitsgory is a newly appointed director at the Max Planck Institute for Mathematics in Bonn. He will join the three active directors Gerd Faltings, Peter Teichner, and Peter Scholze in July 2021.

Dennis Gaitsgory was Born in 1973 in Moldava, a republic of the Soviet Union at the time. He studied at Tel Aviv University under Joseph Bernstein from 1990–1996, where he received his doctorate in 1997 for a thesis on "Automorphic Sheaves and Eisenstein Series". In the academic years 1996/97 and 1998/99 he was at the Institute for Advanced Study in Princeton. In 2001 he became Associate Professor at the University of Chicago before joining the faculty of Harvard University in 2005.

Danica Kosanović Receives Hausdorff Memorial Prize

Posted in

Danica Kosanović is one of the two prize winners of the Hausdorff Memorial Prize for the best PhD thesis in mathematics at the University of Bonn in 2019/2020. In her thesis on “A geometric approach to the embedding calculus knot invariants”, which was supervised by Peter Teichner, she proved a 30 year old conjecture about invariants of classical knots.
