Jan 19, 2016 at 23:20 | comment | added | pro | isn't Sym k = k[x]? | |
Jan 19, 2016 at 22:58 | comment | added | Sasha | I mean Spec of Sym of dual. Why would that be wrong for T a point? It would say that morphisms from $X$ to $\mathbb{A}^1$ are the same as elements of the set $\Gamma(X,\mathcal{O}_X)$, which is correct, no? | |
Jan 19, 2016 at 19:53 | comment | added | pro | what do you mean by interpreting $\Gamma(X,O)$ as a scheme as usual? Do you mean taking Spec of it, or Spec of Sym of its dual? If the latter, then it's false (eg take X to be projective space and T = Spec k). | |
