| Aug 2, 2015 at 15:19 | comment | added | O-Ren Ishii | This is very nice. Thank you for sharing this. What reference would you recommend for the New Intersection Theorem (I've looked it up from some slides online)? Also, why does there exist a $\psi$ locally on $Y$? Is this some generalization of the fact that a regular local ring of dimension $n$ has a free resolution of length $\le n$? | |
