Date: 
Thu, 2020-03-12 12:00 - Fri, 2020-03-13 17:00
Location: 
MPIM Lecture Hall

This is the fourteenth of a series of  short workshops jointly organized by the Geometry/Topology groups in Bonn, Nijmegen, and Utrecht, all situated along the Lower Rhine. The focus lies on the development and application of new structures in geometry and topology such as Lie groupoids, differentiable stacks, Lie algebroids, generalized complex geometry, topological quantum field theories, higher categories, homotopy algebraic structures, higher operads, derived categories, and related topics.

Professor Peter Scholze received the Bundesverdienstkreuz (Great Cross of Merit) from the Federal President of Germany, Frank-Walter Steinmeier. The ceremony took place at Schloss Bellevue in Berlin (Federal President’s principal official residence). The Federal President's office declared that due to his exceptional achievements Peter Scholze was a motivating role model for future generations of his research area.

 

A new street in Bonn Poppelsdorf is named after the MPIM founder, Professor Friedrich Hirzebruch (1927-2012)

We are pleased to announce that the city of Bonn decided on September 19, 2019 to name a new street in Bonn after our institute founder, Professor Friedrich Hirzebruch. The street is called Friedrich-Hirzebruch-Allee and is located in the Poppelsdorf campus between the corner of the Carl-Troll-Strasse/Karlrobert-Kreiten-Strasse and the new center of lecture halls, Endenicher Allee 19c.

Pentagramma Mirificum (the miraculous pentagram) is a beautiful geometric construction studied by Napier and Gauss. Its algebraic description yields the simplest instance of cluster transformations, a remarkable family of recurrences which arise in diverse mathematical contexts, from representation theory and enumerative combinatorics to theoretical physics and classical geometry (Euclidean, spherical, or hyperbolic).

Michael Atiyah 1929-2019

Posted in

The Max Planck Institute for Mathematics mourns the death of Michael Atiyah, one of the giants of mathematics. Over many decades Michael Atiyah was a frequent and welcome visitor, inspiring speaker, ingeneous collaborator, and friend to many of the mathematicians in Bonn. Together with Friedrich Hirzebruch, MPIM's founding director and one of Michael's oldest and closest friends, he laid the foundations for topological K-theory, an important tool in algebraic topology. He almost always gave the opening lecture of the annual Mathematische Arbeitstagung in Bonn, from its beginning in 1957.
