| Aug 5 at 12:40 | comment | added | user267839 | @WillSawin: Yes, let add finiteness to covers we considering. How would one in this case argue? | |
| Aug 5 at 12:35 | comment | added | Will Sawin | The cover of a scheme by its affine open sets is faithfully flat and every invertible sheaf on an affine scheme is ample. So there is no criterion of this type. The only class of faithfully flat cover where I think such a criterion might work non-vacuously is a finite faithfully flat cover. | |
