Workshop on Interactions between Group Theory and Homotopy Theory — Focus Program on Algebraic Topology In memory of Fred Cohen
28 jul 2025 - 01 aou 2025 • Toronto, Ontario, Canada
Organisateur:
The Fields Institute for Research in Mathematical Sciences
Résumé:
Group theory and topology have a long and rich history of interaction. This workshop will bring together experts working on different aspects of this interaction in order to share ideas and boost the development of new methods that can be applied to the topology of configuration spaces, braid groups, mapping class groups and manifolds, and spaces of commuting elements.

ESI Workshop — Eisenstein Series, Spaces of Automorphic Forms, and Applications
01 sep 2025 - 05 sep 2025 • Universität Wien, Autriche
Organisateur:
Erwin Schrödinger International Institute for Mathematics and Physics (ESI)
Résumé:
This program will focus on several aspects of the theory of automorphic forms with an emphasis on the relations among the internal structure of spaces of automorphic forms, the Langlands functoriality principle, automorphic L-functions, and questions in geometry, in particular, those regarding locally symmetric spaces. These are associated with arithmetic subgroups of a given reductive algebraic group G dened over analgebraic number field. Special attention is given to the theory of Eisenstein series and their ubiquitous role within the theory of automorphic forms.

Frontiers of Lie Theory: Computational Aspacts and Applications
28 sep 2025 - 04 oct 2025 • Będlewo, Pologne
Organisateur:
Banach Center
Résumé:
Since its origins in the work of Sophus Lie (now more than a century ago), Lie theory has seen tremendous developments and is now fundamental in many areas of mathematics (like group theory, geometry, symmetric spaces etc) and physics (quantum mechanics, particle physics, theory of gravity). Nowadays there are specialized computer packages such as LiE, the Atlas project, the package Chevie for GAP3, the program ChevLie. Also the more general purpose computer algebra systems GAP4, MAGMA and SageMath have large libraries for dealing with various objects that are central to Lie theory.

Diagrammatic Categorification
20 oct 2025 - 24 oct 2025 • Providence, RI, États-Unis
Organisateur:
Institute for Computational and Experimental Research in Mathematics, Brown University, Providence, RI (ICERM)
Résumé:
The diagrammatic approach has its origins in the discovery of new quantum invariants of knots and links in the 1980s. Crane and Frenkel raised the idea of categorifying quantum groups, hence, link invariants, already in the 1990s, and this vision prompted the development of powerful link homology theories such as Khovanov-Rozansky homology. The categorification of quantum groups involves Khovanov-Lauda-Rouquier algebras, which are often presented diagrammatically. They are a building block for Kac-Moody 2-categories, which categorify Lusztig’s modified integral form for quantized enveloping algebra. There have been many remarkable developments in this direction in the last few years, including the introduction by Webster of more general algebras categorifying tensor products, DG versions of these algebras which categorify Verma modules, and p-DG versions which are being used to categorify link invariants at roots of unity. 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.

Webs in Algebra, Geometry, Topology and Combinatorics
08 dec 2025 - 12 dec 2025 • Providence, RI, États-Unis
Organisateur:
Institute for Computational and Experimental Research in Mathematics, Brown University, Providence, RI (ICERM)
Résumé:
Webs are diagrammatic tools for representing complex calculations graphically. These diagrams first arose from the representation theory of classical groups, and they have since become important in disparate areas of mathematics. In representation theory, they encode morphisms of quantum groups. In topology, webs give rise to powerful link invariants. In algebra and geometry, Kuperberg's \(mathrm{sl}(3)\) web bases have important relationships with the theory of cluster algebras and affine buildings. In combinatorics, they explain certain dynamics on Young tableaux. Recent work by Gaetz--Pechenik--Pfannerer--Striker--Swanson introduced an \(\mathrm{sl}(4)\) web basis that has exploited and extended exciting connections between webs, plabic graphs, and crystals. There are further connections to total positivity, duality conjectures for cluster algebras and mirror symmetry.

Workshop — Groups, representations, cohomology: Celebrating the mathematical contributions of Dave Benson, on the occasion of his 70th birthday
08 jui 2026 - 12 jui 2026 • ICMS, Bayes Centre, Edinburgh , Royaume-Uni
Organisateur:
The International Centre for Mathematical Sciences (ICMS)
Résumé:
This workshop centers on the representation theory of finite groups and closely related structures. Some areas of the field are well-established and classical, while others include subjects born only recently. All are being rapidly evolving and actively explored by diverse research communities. These communities, often located in different regions around the world, offer distinct perspectives and approaches to the subject. A central aim of the workshop is to bring together experts and early-career researchers from these various groups, providing a forum to share progress, exchange ideas, and ask each other questions. The workshop also offers an opportunity to celebrate Dave Benson’s 70th birthday, which falls in December 2025. Dave’s work has had a profound influence on many of the themes represented at this meeting, and we look forward to honoring his contributions during the event.
Sujets:
Cohomology and modular representation theory of finite groups; Hochschild cohomology; Algebraic topology; Tensor-triangular geometry; Finite tensor categories
