## On the zero locus of a normal function

Abstract: Using the theory of degenerations of mixed Hodge structure,
we prove that the zero locus of a normal function defined on a Zariski
open subset of a smooth complex projective variety S is algebraic in
the case where S is a curve, and discuss progress on the case where
dim S>1. As part of this program, we construct limit Abel-Jacobi maps.
