Moduli space of cubic threefolds via intermediate Jacobians
Abstract: A result of Clemens and Griffiths says that a smooth cubic threefold can be
recovered from its intermediate Jacobian. I will discuss the possible
degenerations of these abelian varieties, and give a description of the
compactification of the moduli space of cubic threefolds obtained in this
way. I will then compare this compactification to other known
compactifications. The situation is quite similar to that of the moduli
spaces of low genus curves. This is joint work with S. Casalaina-Martin.
