| Jan 12, 2015 at 13:56 | comment | added | Jan Grabowski | @QiaochuYuan Certainly, I agree. But I wanted to have a synergy between my stories for the representation theory and for the algebraic geometry, so it seemed a natural question to ask. | |

| Jan 12, 2015 at 13:02 | comment | added | Qiaochu Yuan | There are other ways to motivate the derived category than touting it as a good invariant, an important one being defining derived functors on them. | |
| Jan 12, 2015 at 12:46 | comment | added | მამუკა ჯიბლაძე | Sort of aside maybe - there seems to be lot of additional structure, simplest one being derived tensor product. I wonder whether there are theorems describing all of the structure involved. | |
