Abel-Jacobi map, integral Hodge classes and decomposition of the diagonal
Given a smooth projective n-fold Y , with H3,0(Y ) = 0, the Abel-Jacobi map induces a morphism from each smooth variety parameterizing codimension 2-cycles in Y to the intermediate Jacobian J(Y ), which is an abelian variety. Assuming n = 3, we study in this paper the existence of families of 1-cycles in Y for which this induced morphism is surjective with rationally connected general fiber, an...
متن کاملThe 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 from the group of r-cycles on a complex variety that are algebraically equivalent to zero to a certain “Jacobian” built from the Lawson homology groups viewed as inductive limits of mixed Hodge structur...
متن کاملArithmetic Hodge Structure and Higher Abel-jacobi Maps
In this paper, we show some applications to algebraic cycles by using higher Abel-Jacobi maps which were defined in [the author: Motives and algebraic de Rham cohomology]. In particular, we prove that the Beilinson conjecture on algebraic cycles over number fields implies the Bloch conjecture on zero-cycles on surfaces. Moreover, we construct a zero-cycle on a product of curves whose Mumford in...
متن کاملThe Jacobian, the Abel-jacobi Map, and Abel’s Theorem
A natural question to ask is: which divisors of degree 0 do not arise from meromorphic functions? The answer is given in a theorem of Abel, which we will present here. Since each divisor up to linear equivalence also corresponds to an isomorphism class of line bundles of degree 0, we will also be able to use Abel’s theorem to classify degree 0 line bundles on X as points of a complex torus call...
متن کاملNori’s construction and the second Abel-Jacobi map
Here a sheaf F on X is weakly constructible if X is the disjoint union of finite collection of locally closed subschemes Yi defined over k such that the restrictions F |Yi are locally constant. Beilinson ([1], Lemma 3.3) proves this fact in all characteristics of the base field. Based on Theorem 1.1 Nori shows that affine k-varieties have a kind of “cellular decomposition”. In section 2 of this...
