comment Equivalence of continuous functions
That doesn't seem related? Germ is a local property (agreement of two functions in a neighbourhood) whereas this is conceptually almost the opposite: the same preimage sets regardless of how the functions behave within those sets.

I don't want to forget the additive identity, only the multiplicative identity. The space is also one-dimensional as it is isomorphic to F, but there is no canonical isomorphism.
