Apr 13, 2010 at 17:07 | comment | added | Hailong Dao | Hi again, thanks for the new post. This looks really interesting, but I am a little confused about your $Y$. Do you mean something like $Y=Spec k[x,y,z]/(x^2+y^2+z^2)$? Then I think $Cl(Y)=\mathbb Z/(2)$. | |

Tried to correct the errors in the earlier example

Apr 12, 2010 at 13:37 | comment | added | Hailong Dao | The class group of the local ring the origin of the cone over Y is $Cl(Y)/\mathbb Z(H)$, where $H$ is the hyperplane section. So I don't think your example works. | |
