Title: The de Rham side of the mirror story
Time: 2009-03-26 (Thu.)  15:00 - 16:00
Abstract: Given a family of Calabi-Yau varieties of relative dimension 3, there is a differential equation attached to it. Under certain conditions, one can define the so-called mirror map and the Yukawa coupling from the differential equation. It is conjectured that the two maps admit some integrality properties. I will try to explain the story and indicate a way to establish the integrality.
