| Apr 24, 2010 at 12:58 | comment | added | Jim Humphreys | @Noah: The examples I'm thinking about arise in various branches of representation theory, but "abelian category" is a good setting in view of Freyd-Mitchell embedding and recent work in other areas. | |

| Apr 24, 2010 at 6:08 | comment | added | Theo Johnson-Freyd | I think this is a good question, but as written I think it is too discussion-y/argumentative? Rarely do I think a question can be improved by writing less: maybe it would be better to more clearly separate your (very good) question from your thoughts on it and other motivation? | |

"module category" doesn't mean what you think it means
|
| Apr 24, 2010 at 0:05 | comment | added | Noah Snyder | By "module category" do you mean "the category of modules over a ring"? This isn't the usual definition of a "module category" so I'm going to edit your question accordingly. Please feel free to revert and clarify if I've messed up your question. | |
