| Sep 16, 2016 at 2:04 | comment | added | Marc Hoyois | This can fail already for $X=\operatorname{Spec}(k)$: fields have no cdh cohomology, but $H^*_h(X,\mathbb Z/l)$ always agrees with etale cohomology. A reference for the latter fact is Voevodsky's thesis math.uiuc.edu/K-theory/0031/H1.pdf. | |
