A typical example is the category of schemes with morphisms of finite type. A typical non-example is the category of noetherian schemes with all morphisms of schemes. | |
| Jun 18, 2013 at 3:47 | comment | added | Daniel Moskovich | This is a great quote- thanks! But it sounds to me like Grothendieck is making a different point here, about how to judge a category, rather than about relative value of "good category" vs. "good objects" or even "good morphisms". | |
