Events

The Arbeitsgemeinschaft (study group) is a series of meetings in Oberwolfach. It mainly addresses to non-specialists who want to broaden their outlook on mathematics and to early career mathematicians who wish to enter a field for future research. Experts are also welcome. The idea is “learning by teaching”. Participants have to volunteer for one of the lectures described in the program. After the deadline for application the organizers choose the actual speakers to give them enough time to understand the subject and to prepare for their lectures. An outline of the program can be found on the website of the event. Deadline for applications: 1 June 2025

Aim of the School is to bring together young students and researchers with experts in the research areas of global analysis, spectral theory, mathematical physics and their interplay. The school consists of four mini-courses leading towards a broad understanding of current research topics from different perspectives. The mini-courses will be aimed at a broad audience. Speakers of the mini-courses: * Nelia Charalambous on "The spectrum of geometric operators on noncompact manifolds" * Jeffrez Galkowski on "The high energy behavior of Laplace eigenfunctions: applications of geodesic beams" * Frédéric Rochon on "L2-cohomology of complete hyperKähler metrics" * Alexander Strohmaier on "Spectral Theory on Spacetimes"

The BELIEF school is a biennial event organized by the Belief Functions and Applications Society (BFAS) that offers a unique opportunity for students and researchers to learn about fundamental and advanced aspects of the theory of belief functions (also referred to as Dempster-Shafer theory, or evidence theory), a formalism for reasoning with uncertainty. The school will be organized around a set of lectures by prominent researchers. Lectures will gradually tackle basic to more advanced theoretical concepts. They will also highlight the links with other uncertainty theories such as random sets and possibility theory, and present applications of belief functions in various domains including machine learning, information fusion, statistical inference and materials science. Financial Support The Belief Functions and Applications Society (BFAS) is offering several grants that cover the school registration fees (which include the tuition fees, lunches, coffee breaks and the social event).

How do we model complicated phenomena including fluids like phase transition and turbulence by using differential equations?How do we analyze such equations which are often challenging? The weak-long Oberwolfach Seminar will be devoted to such questions. The target audience is PhD students or post-doctoral researchers wishing to be quickly immersed in this modern, active research area. Deadline for application: 15 July 2025

How can we study algebraic geometry, modular representation theory, and stable homotopy theory at the same time? One answer is given by tensor triangular geometry, which is a young and vibrant area based on viewing symmetric monoidal triangulated categories as geometric objects. The aim of the seminar is to give a comprehensive introduction to the fundamentals of the subject and an overview of recent developments in algebra and topology. There will be a particular focus on triangulated categories associated to finite group actions, for instance equivariant spectra and categories arising from representation theory. The target audience is PhD students and postdocs with a background in homological algebra and/or homotopy theory (e.g. some exposure to derived or triangulated categories) who are keen to learn tensor triangular geometry and be brought up to date with some current research in the subject. Deadline for application: 15 July 2025

Stochastic analysis is a very dynamic field which has undergone numerous developments over the last decades: stochastic differential equations (SDE), stochastic partial differential equations (EDPS), Malliavin calculus… The overall aim of the workshop is to bring together experts from different disciplines related to singular stochastic systems to facilitate the exchange of ideas. The goal is to identify and motivate novel research directions on the well-posedness, dynamical behavior and numerical simulation of singular stochastic (partial) differential equations.

The field of diagrammatic categorification is still in its early stages, but it has already had a significant impact on more traditional mathematics. This workshop aims to unite both established experts and emerging scholars across various domains of diagrammatic categorification, including representation theory, combinatorics, and link homology.

In recent years, modern algebraic geometry, such as moduli spaces and enumeration, has been very successfully applied to combinatorics and tensors, resolving old conjectures, giving easier proofs of classical theorems, and opening new research paths. This seminar will focus on the two main interconnected topics. (1) Interactions between matroid theory, geometry, and intersection theory, as in the recent work of June Huh and beyond, using varieties of complete linear maps and complete quadrics; (2) new invariants of tensors, such as 111-algebra and moduli spaces of tensors from Hilbert schemes of points and its generalisations. The common motive is to associate new intricate invariants to seemingly explicit, structureless objects such as tensors or graphs. Deadline for applications: 1 July 2025

Join us for a three-day workshop on nonlinear partial differential equations in Salzburg, featuring keynote talks by Giovanni Molica Bisci, Nicola Fusco, Antonio Iannizzotto, Carolin Kreisbeck, Jan Kristensen, Anastasia Molchanova, Raffaella Servadei, and Ulisse Stefanelli, alongside short contributed talks by PhD students and postdocs.
