Informal Friday Seminar: Nehme
Representation theory of Lie (super)algebras, Schur--Weyl duality and KLR
algebras
Jonas Nehme, University of Bonn
Informal Friday Seminar, 27th February 2026
9 am – 11 am, SMRI Seminar Room (A12 Macleay Room 301)
Abstract: : In contrast to finite dimensional representations of
semisimple Lie algebras, the super world is not semisimple anymore. I will present an
approach via Schur--Weyl duality to obtain diagrammatic descriptions of these
categories. On the road we will encounter e.g. KLR algebras and many nice
combinatorics evolving around partitions. At the heart of this approach lie many
intricate diagrammatic basis theorems, where I think some machine learning/AI approaches
might be feasible.
The Informal Friday Seminar is a space where members of our research group can explain
interesting things to each other in a casual setting. The rules of the seminar are the
following:
- Any question/additional explanation from the audience is
allowed.
- Ego out the window.
- Examples, examples, examples.
The seminar is intended to be conversational, so come ready to engage. If you choose to
give an IFS talk, it's important to know that part of the IFS philosophy is that
learning is not linear. In other words, it if perfectly acceptable to give a
talk that is a prerequisite for a talk that already happened. For IFS updates, please
