| Jul 10, 2014 at 8:26 | comment | added | user55846 | I agree with you, Dag Oskar Madsen. In any case, is it true that $Hom_{R}(E(k),k)=0$? and more general, Is it true that $Ext_{R}^{i}(E(k),k)=0$ for all $i\geq 0$?. | |
| Jul 10, 2014 at 8:09 | comment | added | Dag Oskar Madsen | Since $Hom_{D(R)}(E(k),k)=Hom_R(E(k),k)$, this isn't really a question about the derived category. | |
