Title: Families of perverse sheaves
Abstract: Given a morphism of varieties X -> Y, is there a good definition of a “family of perverse sheaves Fy on the fibers Xy” as y runs through the closed points of Y? It turns out that such a definition has been lurking in the geometric Langlands literature, albeit in an obscured form, for almost twenty years. In this talk, I’ll explain this definition and highlight the many remarkable properties enjoyed by families of perverse sheaves. I’ll also discuss some applications and some open questions.
