Query: Opposite filtrations, variations of Hodge structure, and Frobenius
  modules   In this article we describe three constructions of complex variations of
Hodge structure, proving the existence of interesting opposite filtrations that
generalize a construction of Deligne. We also analyze the relation between
deformations of Frobenius modules and certain maximally degenerate variations
of Hodge structures. Finally, under a certain generation hypothesis, we show
how to construct a Frobenius manifold starting from a deformation of a
Frobenius module.
