| Jul 30, 2012 at 9:14 | comment | added | Jakob | Yes, I hope the parenthetical addition makes it clearer. Indeed, I also don't expect the converse to be true, but I'm looking for a statement that is (true and) somehow close, in spirit, to the converse statement. I.e. I am looking for "Assuming $f^! R = R[n]$, then $M$ is "nice" in some sense." | |

| Jul 29, 2012 at 17:05 | comment | added | Konrad Voelkel | May I suggest you to edit the question to include some conjectural "converse statement"? It took me some time to figure out you probably want something like "if the exceptional inverse image along the constant map is just a shifted-by-dimension constant sheaf, the manifold is smooth". I would guess this is wrong, but I'm not an expert. | |
