| Nov 15, 2009 at 21:55 | comment | added | Benjamin Antieau | What exactly do you mean by the second question? Specifically, what is a weak equivalence? Are you using the model category structure where $X\rightarrow Y$ is a weak equivalence if and only if it induces a weak equivalence on homotopy sheaves? | |
