Four Lectures on Primitive Forms
(An introduction to complex analytic theory)
Prof. Kyoji Saito
(IPMU, the University of Tokyo)
A primitive form is a family of differential forms of top-degree defined
on a family of open complex varieties. It was introduced as a higher
dimensional generalization of the elliptic integral of the first
kind, and its period integral over vanishing cycles are expected to
introduce new class of automorphic forms.
In the last decade, it was getting clear that a primitive form is an
object in complex geometry which is mirror to the Gromov-Witten
invariants in symplectic geometry. From this new categorical view
point, there appear several new trials to reconstruct primitive
forms in a categorical manner in a context of «non-commutative Hodge
In the present series of lectures, I restrict myself to the view point
of the classical complex geometry. We do not assume any prerequisite
knowledge to the audiences except for basic mathematics. However, some
knowledge of complex analytic geometry may be helpful.
