The generalized Hodge and Bloch conjectures are equivalent for general complete intersections, II (1403.3904v1)

Abstract: We prove an unconditional (but slightly weakened) version of the main result of our earlier paper with the same title, which was, starting from dimension $4$, conditional to the Lefschetz standard conjecture. Let $X$ be a variety with trivial Chow groups, (i.e. the cycle class map to cohomology is injective on $CH(X)\mathbb{Q}$). We prove that if the cohomology of a general very ample hypersurface $Y$ in $X$ is ``parameterized by cycles of dimension $c$'', then the Chow groups $CH{i}(Y)_\mathbb{Q}$ are trivial for $i\leq c-1$.
