| Mar 26 at 14:20 | comment | added | Maxime Ramzi | Actually, I realized the answer is no either way. I thought it would be yes if you didn't allow retracts but that's only if the thick closure of $C$ is the whole of $Perf(R)$. | |
| Mar 26 at 12:50 | comment | added | cellular | @MaximeRamzi since you are rising the question, I'm open to all possibilities. What would the answer if we will (will not) allow retracts. | |
| Mar 26 at 12:40 | comment | added | Maxime Ramzi | It depends what you mean by "generated". Do you allow retracts ? | |

| Mar 26 at 12:14 | comment | added | cellular | @pbelmans Thanks I forgot to mention that E is concentrated in degree 0. | |
| Mar 26 at 12:12 | comment | added | pbelmans | The class of $E=R\oplus R[1]$ vanishes, but $E$ generates everything, so this cannot be true. | |
