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 44, conditional to the Lefschetz standard conjecture. Let XX be a variety with trivial Chow groups, (i.e. the cycle class map to cohomology is injective on CH(X)QCH(X)_\mathbb{Q}). We prove that if the cohomology of a general very ample hypersurface YY in XX is ``parameterized by cycles of dimension cc'', then the Chow groups CHi(Y)QCH_{i}(Y)_\mathbb{Q} are trivial for ic1i\leq c-1.
