Abstract: The theory of primitive forms was introduced by Kyoji Saito in early 1980s, which was first known in singularity theory and has attracted much attention in mirror symmetry recently. In this talk, we will introduce a complex differential geometric approach to primitive forms, using compactly supported polyvector fields. Especially, we will explain a perturbative formula of primitive forms and show various computational examples. This is my joint work with Si Li and Kyoji Saito.
