If "d" isn't exterior derivative, I don't see how it's defined. I can't think of any other meaning "d" could have in the context of this discussion. Sorry, I'm just not understanding you - but thank you anyway for trying to explain your thinking.
- impossiblefork 3y agoIt's some kind of formal analogue where you can't drop all terms that become infinitesimal, sort of like a formal power series compared to an actual power series. So something like an exterior derivative where d(df) is not defined to be zero and such terms must be kept.
