Abstract
We study a formal deformation problem for rational algebraic cycle classes motivated by Grothendieck’s variational Hodge conjecture. We argue that there is a close connection between the existence of a Chow‐Kunneth decomposition and the existence of expected deformations of cycles. This observation applies in particular to abelian schemes.
