| May 3 at 10:08 | comment | added | Jef | This would require knowing that the `generic fiber' homomorphism $\text{CH}^p(X)\rightarrow \text{CH}^p(X_K)$ is surjective when restricted to the subgroups of algebraically trivial cycle classes. I don't see an obvious reason why that's true, nor what the definition of such a subgroup of $\text{CH}^p(X)$ would actually be. (Fulton only considers algebraic triviality for varieties over a field.) | |
