Let Y be a smooth complete intersection of three quadrics, and assume the dimension of Y is even. We show that Y has a multiplicative Chow–Künneth decomposition, in the sense of Shen–Vial. As a consequence, the Chow ring of (powers of) Y displays K3-like behaviour. As a by-product of the argument, we also establish a multiplicative Chow–Künneth decomposition for double planes. 
Some new Fano varieties with a multiplicative Chow-K\"unneth decomposition
Let Y be a smooth dimensionally transverse intersection of the GrassmannianGr(2, n) with 3 Plücker hyperplanes. We show that Y admits a multiplicative Chow–Künneth decomposition, in the sense of
Some Motivic Properties of Gushel-Mukai Sixfolds
Gushel-Mukai sixfolds are an important class of so-called FanoK3 varieties. In this paper we show that they admit a multiplicative ChowKünneth decomposition modulo algebraic equivalence and that they


Finite-dimensionality and cycles on powers of K3 surfaces
For a K3 surface S, consider the subring of CH(S^n) generated by divisor and diagonal classes (with Q-coefficients). Voisin conjectures that the restriction of the cycle class map to this ring is
Algebraic cycles and Fano threefolds of genus 8
We show that prime Fano threefolds Y of genus 8 have a multiplicative Chow– Künneth decomposition, in the sense of Shen–Vial. As a consequence, a certain tautological subring of the Chow ring of
Algebraic cycles and Verra fourfolds
This note is about the Chow ring of Verra fourfolds. For a general Verra fourfold, we show that the Chow group of homologically trivial $1$-cycles is generated by conics. We also show that Verra
The Chow Ring of a Cubic Hypersurface
We study the product structure on the Chow ring (with rational coefficients) of a cubic hypersurface in projective space and prove that the image of the product map is as small as possible.
An interesting 0-cycle
The geometric and arithmetic properties of a smooth algebraic variety X are reflected by the configuration of its subvarieties. A principal invariant of these are the Chow groupsCHp(X), defined to be
The properties of a toric variety have strong connection with the combinatorial structure of the corresponding fan and the rela- tions among the generators. Using this fact, we have described explic-
Decomposable cycles and Noether-Lefschetz loci
We prove that there exist smooth surfaces of degree d in projective 3-space such that the group of rational equivalence classes of decomposable 0-cycles has rank at least the integer part of (d-1)/3.
We show that the Chow group of 0-cycles on a K3 surface contains a class of degree 1 with remarkable properties: any product of divisors is proportional to this class, and so is the second Chern
The Fourier Transform for Certain HyperKähler Fourfolds
Using a codimension-1 algebraic cycle obtained from the Poincare line bundle, Beauville defined the Fourier transform on the Chow groups of an abelian variety A and showed that the Fourier transform
