Infinitesimal deformation of Deligne cycle class map
Sen Yang
In this note, we study the infinitesimal forms of Deligne cycle class maps. As an application, we prove that the infinitesimal form of a conjecture by Beilinson is true.

On the image of the Abel-Jacobi map
Sen Yang
We prove and generalize an observation of Green and Griffiths on the infinitesimal form of the Abel-Jacobi map. As an application, we prove that the infinitesimal form of a conject…
