I'd been trying to make something like that work (to ultimately reduce to something with affine space in dim > 0), but I kept getting stuck. Then I gave up and just posted the partial idea as comment to your earlier answer. Good to see this kind of strategy works in the end, even simpler than the P^1 case. Wicked, indeed. | |
