TITLE: Constructible sheaves and Lagrangian cones

ABSTRACT: The Kashiwara-Schapira theory of singular support for constructible sheaves, which I will assume is not familiar to anyone, can be used to attach a triangulated category to a Lagrangian cone in R2n. I’ll describe the categories you get for some examples in R2, R4, and R6. The examples are all special, or else conjectured to be special; I wish I knew how to put that to use. Joint work with Eric Zaslow.
