Women in Automorphic Forms (WIAF)

The WIAF conference highlights recent, excellent developments on automorphic forms in all aspects. These forms and functions are intimately related to the geometry at infinity of symmetric spaces. And hence they are of utmost interest in several projects within the SPP 2026. With the WIAF conference we bring together young researchers with excellent senior researchers in order to foster communications of new results and to identify fascinating new directions of further research on automorphic forms and their applications. This conference is specially, but not exclusively, addressed to female mathematicians.

Dynamics and asymptotics in algebra and number theory (DAAN)

With the DAAN conference we will bring together researchers at the crossroads of algebra, number theory and dynamical systems theory working on similar questions from different perspectives. Of particular importance will be dynamical systems approaches to entities from number theory and algebra in regard to their asymptotic aspects. Some of these entities, in particular Laplace eigenfunctions, as well as several of the techniques and tools play a fundamental role within the SPP 2026, in particular for Project 70 (Spectral theory with non-unitary twists).

Spectral theory and geometry of ergodic Schrödinger operators

The main goal in the spectral theory of ergodic Schrödinger operators is to understand the interplay between the underlying geometry of the space, the dynamics of the system and the spectral properties of the operator. Our school focuses on the so-called minimal or ergodic dynamical systems - where minimality is perceived as the topological analog of ergodicity. If the underlying geometry and dynamics are minimal then the system is determined by the geometric properties at infinity.

Groups and dynamics in geometry

The conference aims to explore the current state-of-the-art at the interface between three core research areas of modern pure mathematics: geometry, dynamical systems, and (geometric) group theory. Individually, all three are well-established and classical areas, which are very active fields of mathematics all over the world. However, some of the most striking recent mathematical advances have stemmed from deep interactions between them – both actual mathematical connections, as well as the international and cooperative community of mathematicians involved.

Interdisciplinary junior scientist workshop: Mathematical General Relativity

This interdisciplinary two week workshop in Mathematical General Relativity is aimed at young researchers such as postdocs, doctoral and masters students with a background in General Relativity and in PDE Theory, Differential Geometry, or Classical Mechanics and with an interest in interdisciplinary exchange between mathematicians and physicists. It will feature four Interdisciplinary mini lecture series with exercise sessions by Stefan Czimek (Universität Leipzig), Domenico Giulini (Universität Hannover), Thomas Körber (Universität Wien) and Anna Sakovich (Uppsala Universitet).

Modern advances in geometric group theory

The focus of this workshop is modern advances in the study of infinite groups, under a variety of contexts, many of them related to topology. There is a long history of interaction between groups, geometry, and topology (e.g. Dehn's problems on finitely presented groups) going up to the present day (e.g. use of cubulated groups in Agol's Breakthrough Prize work on 3-manifolds). There have been further advances and new ideas recently in the study of homeomorphism groups, mapping class groups, one-relator groups, right-angled Artin groups, random groups, and the concept of finding "fibrings" of groups, to name just a few. The goal is to bring together experts to explain their work, and then try to use their new methods in neighbouring areas. By doing this we can accelerate the development of new mathematics, and work on solving problems using state of the art techniques.
