The issue is that this isn't obviously functorial. I think the naive definition is not functorial (I haven't checked carefully though). I don't have a great intuition for these sorts of things myself. | |

| Oct 14 at 22:36 | comment | added | Jonathan Beardsley | Ah thanks very much! Do you have any sense of how we are supposed to think about the relationship between vector spaces and combinatorial geometries? I guess there is a functor from vector spaces over a field 𝔽 to K-modules? | |
