Abstract:
We prove an unconditional (but slightly weakened) version of the main result of \cite{voisingenhodgebloch}, 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 hypersurface $Y$ in $X$ is parameterized by cycles of dimension $c$'', then the Chow groups $CH_{i}(Y)_\mathbb{Q}$ are trivial for $i\leq c-1$.

Keywords: Coniveau, Chow groups, Hodge structures.
