You can classify representations of simple Lie groups using Dynkin diagrams, but you can also classify representations of ‘classical’ groups using Young diagrams. Hermann Weyl wrote a whole book on ...

Jun 1, 2025 Todd Trimble and I wrote a paper on characterizing classical groups (and monoids) in terms of their 2-rigs of representations.

Jun 8, 2009 You can now see the introduction to a paper James Dolan is writing about algebraic geometry for category theorists. You can also see 5 lectures he gave on this topic.
