Nov 19 at 17:01 | comment | added | Z. M | Oh, what I had in my mind was incorrect. I thought of stable envelope of additive categories, but here, we need stable envelope of exact categories. | |
Nov 19 at 14:07 | comment | added | Victor Saunier | @Z.M unless I misunderstand what you ask, the above-cited theorem precisely says the two agree. | |
Nov 19 at 12:26 | comment | added | Z. M | I am confused. What is the relation between the bounded derived category of a small abelian category with its stable envelope. | |
Nov 19 at 8:32 | comment | added | Victor Saunier | As David's answer below illustrates, the large derived bounded category is often constructed as a localisation, and this means one should probably be careful with the set-theory. For example, if your abelian category is locally presentable, then you should be able to reduce to the small case. | |
Nov 19 at 7:48 | comment | added | Lin Chen | I agree. But in the classical theory, people also considered unbounded derived category of small abelian categories. For instance, arxiv.org/pdf/2003.11261. | |
