A very nice paper by Levine on the homotopy coniveau filtration.

arXiv:0907.3535 Coniveau filtrations and finite dimensionality for pure motives from arXiv Front: math.AG by Charles Vial Let be a smooth projective variety over a field . We define a coniveau filtration – a priori different from the usual coniveau filtration – on the singular cohomology of with rational coefficients. If satisfies the Lefschetz conjecture B, we prove that the projectors on the filtered pieces of the cohomology of are induced by algebraic correspondences. If moreover is finite dimensional in the sense of Kimura (for example, could be any abelian variety or any finite quotient thereof) the Chow motive of admits a refined Chow-Künneth decomposition lifting the coniveau grading on the cohomology of and we study the behavior of the Chow groups of under this decomposition. As an application, we give several conjectural descriptions of the rational Chow groups of depending on the support of the cohomology groups of . We also consider the case where is an arbitrary field. Results valid in characteristic zero extend to positive characteristic if one is ready to admit that the Lefschetz conjecture holds in general.
