Hmmm... I don't see anything from a quick read of the code why this is
going wrong. I'll take a more detailed look today.
Best,

Hello everybody,
there is a post-doctoral position in algebraic combinatorics opening in
Lyon (France) next September.
Details can be found here:

Please pass the word to people you know that could be interested. Lyon is a
nice city,
Hi Andrew,

Hey Andrew and Nicolas,
I've probably mentioned this before, but I think we should figure out
how we want to handle categories for representations in general. I would
like this for Lie algebras (equiv. universal enveloping algebras), quantum
groups, and general groups (equiv. group
