A remark on a $3$-fold constructed by Colliot-Th\'el\`ene and Voisin

  author={Fumiaki Suzuki},
  journal={arXiv: Algebraic Geometry},
A classical question asks whether the Abel-Jacobi map is universal among all regular homomorphisms. In this paper, we prove that we can construct a $4$-fold which gives the negative answer in codimension $3$ if the generalized Bloch conjecture holds for a $3$-fold constructed by Colliot-Th\'el\`ene and Voisin in the context of the study of the defect of the integral Hodge conjecture in degree $4$.

A pencil of Enriques surfaces with non-algebraic integral Hodge classes
We prove that there exists a pencil of Enriques surfaces defined over $${\mathbb {Q}}$$ Q with non-algebraic integral Hodge classes of non-torsion type. This gives the first example of a threefoldExpand
Factorization of the Abel-Jacobi maps.
As an application of the theory of Lawson homology and morphic cohomology, Walker proved that the Abel-Jacobi map factors through another regular homomorphism. In this note, we give a direct proof ofExpand
The Walker Abel-Jacobi map descends
For a complex projective manifold, Walker has defined a regular homomorphism lifting Griffiths’ Abel–Jacobi map on algebraically trivial cycle classes to a complex abelian variety, which admits aExpand
An $\mathcal{O}$-acyclic variety of even index.
We give the first examples of $\mathcal{O}$-acyclic smooth projective geometrically connected varieties over the function field of a complex curve, whose index is not equal to one. More precisely, weExpand

Torsion 1-cycles and the coniveau spectral sequence
We relate the torsion part of the Abel-Jacobi kernel in the Griffiths group of 1-cycles to a birational invariant analogous to the degree 4 unramified cohomology and an invariant associated to theExpand

Cohomologie non ramifiée et conjecture de Hodge entière
Building upon the Bloch–Kato conjecture in Milnor K-theory, we relate the third unramified cohomology group with Q/Z coefficients with a group which measures the failure of the integral HodgeExpand
Torsion cohomology classes and algebraic cycles on complex projective manifolds
Abstract Atiyah and Hirzebruch gave examples of even degree torsion classes in the singular cohomology of a smooth complex projective manifold, which are not Poincare dual to an algebraic cycle. WeExpand
The Torsion of the Group of 0-Cycles Modulo Rational Equivalence
In this work we continue the study of rational equivalence of O-cycles on nonsingular projective varieties over an algebraically closed field k, which we began in [13], [14]. The main result of thisExpand
On certain exterior product maps of Chow groups
This map is most familiar in the case k = K. However, it is worth investigating and is sometimes more easily understood when k ⊂ K has positive transcendence degree. This is illustrated by our mainExpand
The morphic Abel–Jacobi map
The morphic Abel-Jacobi map is the analogue of the classical Abel-Jacobi map one obtains by using Lawson and morphic (co)homology in place of the usual singular (co)homology. It thus gives a map fromExpand
