| Oct 12, 2009 at 19:13 | comment | added | Ben Webster♦ | By the way, I think you've made a bit too strong a claim about Hodge numbers. Think about A^1 versus A^1 minus a point unioned with a point. You're right that weighted Euler characteristic is invariant under scissors congruence, but I'm not sure if you can get much more out of Hodge theory | |
| Oct 12, 2009 at 18:34 | comment | added | David Rydh | The ring, before inverting the Lefschetz motive L=[A], is usually called the Grothendieck ring of varieties. It is known that it has zero-divisors (at least in char. 0). A presentation of this in terms of generators and relations has been given by F. Bittner (arxiv:math/0111062v1). I think that it is common to pass to certain completions of the ring with respect to the Lefschetz motive. | |
