Timeline for The "derived drift" is pretty unsatisfying and dangerous to category theory (or at least, to me)

Dec 30, 2017 at 12:41 | comment | added | Julien Grivaux | I would add onother answer in the list : "discuss of HTT with Yonatan in person". I had many doubts concerning all this homotopical stuff. I think the best way to be convinced is to study a classical problem that leads you to nontrivial homotopical issues (this is what happened to me). Then you start wandering on a weird road, and you discover that each stone on this road has a "raison d'être". Then suddenly all the stuff you've heard in conferences, seen in books, and often thought to be abstract nonsense, starts to have a meaning because you understand WHY it was built for. | |

Dec 26, 2017 at 17:15 | comment | added | Leonid Positselski | There must be quite a few open problems in nonderived category theory, of course. Some of them are listed at the end of the Adamek-Rosicky book on locally presentable and accessible categories (some of these may have been solved since the book's publication). My favorite one lately is this: does there exist a locally presentable abelian category with enough injective objects that is not a Grothendieck category? Perhaps somebody knows an answer to this, and it is just me who doesn't know, but I doubt it. | |
