    • 2416 - Hochschild (Co)Homology and Applications 

      [OWR-2024-20] Workshop Report 2024,20 (2024) - (14 Apr - 19 Apr 2024)
      In 1945 Gerhard Hochschild published "On the cohomology groups of an associative algebra" in the "Annals of Mathematics" and thereby created what is now called Hochschild theory. The subject not only provides interesting ...

    • 2405a - Mini-Workshop: Artin Groups meet Triangulated Categories 

      [OWR-2024-4] Workshop Report 2024,4 (2024) - (28 Jan - 02 Feb 2024)
      Artin and Coxeter groups are naturally occurring generalisations of the braid and symmetric groups respectively. However, unlike for Coxeter groups, many basic group theoretic questions remain unanswered for general Artin ...

    • 2405b - Mini-Workshop: Bridging Number Theory and Nichols Algebras via Deformations 

      [OWR-2024-5] Workshop Report 2024,5 (2024) - (28 Jan - 02 Feb 2024)
      Nichols algebras are graded Hopf algebra objects in braided tensor categories. They appeared first in a paper by Nichols in 1978 in the search for new examples of Hopf algebras. Rediscovered later several times, they ...

    • 2415a - Mini-Workshop: Growth and Expansion in Groups 

      [OWR-2024-17] Workshop Report 2024,17 (2024) - (07 Apr - 12 Apr 2024)
      The aim of the workshop was to give a panoramic view of the main lines of research on various aspects of growth and expansion in finite groups. The main topics included: diameter bounds for Cayley graphs of alternating and ...

    • 2447c - Mini-Workshop: Infinite-dimensional Kac-Moody Lie Algebras in Supergravity and M Theory 

      [OWR-2024-53] Workshop Report 2024,53 (2024) - (17 Nov - 22 Nov 2024)
      This mini-workshop explores the role played by infinite-dimensional Lie algebra of Kac-Moody type in supergravity and M theory. Deep conjectures about the role of affine, hyperbolic and other indefinite Kac-Moody algebras ...

    • 2449 - Representations of p-adic Groups 

      [OWR-2024-54] Workshop Report 2024,54 (2024) - (01 Dec - 06 Dec 2024)
      Representation theory of $p$-adic groups is a topic at a crossroads. It links among others to harmonic analysis, algebraic geometry, number theory, Lie theory, and homological algebra. The atomic objects in the theory ...
