Author's Comments: We examine the infinitesimal period relations of a
3-fold with trivial
canonical bundle and show that they represent an
exterior differential
system on the higher period domain that is the first
prolongation of a
contact system on a `de-prolonged' period domain.
This has some interesting
consequences for relations between the so called
A-periods and B-periods,
showing that they can be expressed in terms of a
single `potential' function.
Of course, in recent years, 3-folds with trivial
canonical bundle have
become a central part of string theory. The literature on
these complex
manifolds and their geometry and deformation theory
has seen an explosive
growth, which I am not competent to catalog. I would
suggest that you contact
my colleague, D. Morrison (drm@math.duke.edu), if you
want pointers to
a survey article.
