The Fourier transform for certain hyperKaehler fourfolds
Mingmin Shen,Charles Vial +1 more
TL;DR: In this paper, it was shown that the Fourier transform induces a decomposition of the Chow ring of hyper-Kahler varieties, which is equivalent to the Hilbert scheme of length-$2$ subschemes on a K3 surface.

Algebraic Cycles and Fibrations
TL;DR: In this article, the authors studied the Chow groups of X in terms of the Chow group of B and of the fibres of f and showed that when X and B are smooth projective and when f is a flat quadric fibration, the Chow motive is built from the motives of varieties of dimension less than the dimension of B.

Projectors on the intermediate algebraic jacobians
TL;DR: In this article, the authors constructed mutually orthogonal idempotents in CHd(X X) Q whose action on algebraically trivial cycles coincides with the Abel-Jacobi map.

Remarks on motives of abelian type
TL;DR: In this paper, it was shown that a Chow group of algebraically closed fields is of abelian type if and only if it is spanned by the Chow groups of products of curves.
