Conference on "New Perspectives on Stable Homotopy and Beyond", September 7-11, 2026

The goal of this conference is to bring together researchers working in and around stable and chromatic homotopy theory, higher categories, and their geometric counterparts. It will serve both to highlight recent advances in these fields and to celebrate the fundamental contributions of Neil Strickland to their development.

Title: Covering a curve
Abstract: Aimed at a general audience, the talk presents results and approaches to an unsolved problem in extremal geometry. 

Preceded and followed by musical contributions from the following artists:

Bonn graduate and Fields medallist Maryna Viazovka will deliver the Friedrich Hirzebruch lecture 2026 on February 24, at 18:30h at the University Club Bonn. The annual Friedrich Hirzebruch Lecture is jointly organized by the Max Planck Institute for Mathematics and the Hausdorff Center for Mathematics. The lectures are for a general audience and aim at illustrating the relation between mathematics and art, society, and other fields. If you would like to attend, you are kindly requested to register here:

Conference on "Interactions between higher algebra, manifolds and functor calculus", May 18-22, 2026

Functor calculus serves as a systematic method for approximating functors by their “polynomial” counterparts. These approximations often allow for interesting new computations in homotopy theory and geometry. For example, in the setting of manifolds, the work of Goodwillie–Klein–Weiss enables one to extend classical computations of spaces of embeddings beyond traditional stable ranges.

ChaBONNty conference, June 29 - July 3, 2026

The endeavour of provably computing rational points on curves stretches back millennia. In the last years the method of Chabauty and Coleman has seen major breakthroughs. The method itself has remarkable applications and currently there are several exciting generalisations being actively developed and applied. In addition to invited talks by established names in the field and an open problem session, we will offer speed talks to young researchers to advertise their work.
