comment Characters of cuspidal representations
Thanks you, I knew it was due to Deligne but for some reason I thought it was unpublished.

Yes, sorry, I'll correct it now.

Sorry, why is there such a vector $v$?

comment Characters of cuspidal representations
Sure, but my statement is much simpler than that and was probably known already 40 years ago.

comment $(L, \nabla)$ comes from a $G$-bundle with connection for some abelian algebraic subgroup $G \subset GL(n)$?
Actually, I am not sure about the last part: since the reduction to Borel is not canonical I don't see how to use Tannakian formalism. But I agree that the question was for $GL(n)$ (I missed that part).

This is a good argument, but I think it only gives a proof for $G=GL(n)$.

comment Homological dimension of Joseph quotients
I think Tony doesn't know the answer (and this question is definitely not discussed in his 1976 paper). At first I thought that the homological dimension should always be finite but it now seems to me that for $so(8)$ I have a very roundabout argument which proves that it can't be so...
