| Aug 12, 2015 at 14:57 | comment | added | lokodiz | I'm assuming that the global dimension of $R$ is finite, so that every $R$-module has finite injective dimension. However, I'm not assuming commutativity. | |
| Aug 12, 2015 at 14:55 | comment | added | Jason Starr | So that I understand: are you assuming that every $R$-module has finite injective dimension? If so, at least in the commutative, Noetherian case, that is equivalent to assuming that $R$ is a regular ring, cf. Theorem 19.2 of Matsumura and Lemma 2 immediately preceding). | |
