Refining the Abel--Jacobi maps
Abstract
Given a smooth projective variety over a field of characteristic zero, we consider the composition of the de Rham cohomology cycle class map over from the Chow group , where is the field of fractions of henselization of the local ring of a smooth closed point of a variety over the field with an appropriate projection: where and are the Hodge and the coniveau filtrations on the de Rham cohomology, respectively. The classical Abel--Jacobi map corresponds to the composition of this homomorphism with the projection to the summand . This homomorphism is not injective, however, its composition with the embedding into the space where and is the maximal ideal, is dominant for any for which the inverse Lefschetz operator is induced by a correspondence.
