| Oct 9, 2010 at 7:53 | comment | added | Torsten Ekedahl | I haven't really thought about what the exact conditions needed to get a model category structure (though I am sure that people have done it). It is quite possible however that there is a model structure where these would be cofibrations. | |

| Oct 8, 2010 at 19:30 | comment | added | domenico fiorenza | so if instead of $\Omega^\bullet(X\otimes \mathbb{R}^n)$ I would use $\Omega^\bullet(X)\otimes \Omega^\bullet_{poly}(\mathbb{R}^n)$ would that work? (here $\Omega^\bullet_{poly}(\mathbb{R}^n$ means polynomial differential forms on $\mathbb{R}^n$) | |
