• Let $X/k$ be a smooth projective geometrically irreducible variety over a field $k$, and $\CH^r(X;\Q) := \CH^r(X)\otimes\Q$ the Chow group of codimension $r$ cycles, modulo rational equivalence. A long standing conjecture, due by S. Bloch and fortified by A. Beilinson, is the existence of a descending filtration on $\CH^r(X;\Q)$, whose graded pieces detect the complexity of $\CH^r(X;\Q)$. The question then is whether one can provide an explicit geometric interpretation of this filtration in the situation where $k\subseteq \C$ is a subfield. This will involve a candidate filtration introduced by Lewis, the concept of cycle induced normal functions, and fields of definition of their zero locus. Towards this goal, we present some partial results, and new lines of enquiry.
