Dec 6, 2009 at 6:07 | comment | added | Pete L. Clark | @David: you're right. In the back of my mind I was wondering about how the Weil restriction of an affine variety became quasi-affine. I'll change it. | |
Dec 6, 2009 at 3:39 | comment | added | David E Speyer | Pete: While this is generally a great answer, the restriction of scalars of (G_m)_C is not A^2_R - {0,0}. Rather, it is Spec R[x,y][ (x^2+y^2)^{-1} ]. These have the same real points, but they are not the same scheme! | |
