| Jul 15, 2014 at 3:27 | comment | added | Mike Shulman | I may end up using "couniversal weak equivalence" despite its disadvantages, though, just because someone else has already used it. (The problems with "flat" are also clear in my other question, since "flat functor" means something very different!) | |
| Jul 15, 2014 at 3:19 | comment | added | Mike Shulman | I agree that "flat" is overused. (Although "sharp" isn't!) Unfortunately "couniversal weak equivalence" is very long, and I cordially dislike the use of "universal" to mean "pullback-stable" (I would prefer to reserve it for "universal properties".) Thanks for the reference though! | |
