comment An elegant description for graded-module morphisms with non-zero zero component
Well, I don't remember. I do remember that I was localizing by these morphisms and that was what I meant by quotienting. Judging by the date, I was probably trying to work out a ncag example. I don't have a clue what it was!

comment Why do we use the commutator bracket for Lie algebra's
Yes, B R this is also a nice point. Although somehow that seems to depend on some of the other facts. In particular, we define Lie alg reps to be compatible with the structure, which is the Jacobi identity...

comment What is the name of the vertical bar?
@Zhen Lin, I would say that depends on the usage, I have no spacing issues for using it in set-builder notation or restrictions. Moreover you forgot to mention the \left. However we are deviating quite far from the point of the question. My comment was meant as a joke.
