| Sep 28, 2023 at 8:48 | comment | added | YCor | Not sure of the meaning of your last edit. Of course the reverse implication is true, but this is trivial (the more interesting "iff" is rather later in the sentence). Also the reverse implication is trivially true in the $F_1$ case. Multiple edits bump the question to the front page and this one wasn't that important. (By the way, it should spell "normally".) | |
