| Aug 10, 2010 at 16:06 | comment | added | Simon Pepin Lehalleur | You might enjoy reading the following : arxiv.org/abs/0912.2110, section 7 and 8, where all this is recast and used to define $DM(S)$ for general bases $S$ (the 6 operation formalism works for rational coefficients and geometrically unibrach schemes). | |
| Aug 10, 2010 at 15:11 | comment | added | anon | Thanks for the over-abundance of interest. A minor corrections: $\ZZ Hilb(X / S, r)$ is indeed a presheaf and cycl defines a morphism of presheaves into $z_{equi}(X / S, r)$ Corollary 3.3.11, see also Theorem 4.2.11 for another intuitive approach to $z, z^{eff}, c, c^{eff}$. For me, the image of cycl would be the most sensible definition and indeed, many proofs in that paper involve essentially reducing to the case where your cycles are in this image. | |
