Abstract:

Let L be an exact Lagrangian submanifold of a cotangent bundle T^*M. If a topological obstruction vanishes, a local system of R-modules on L determines a constructible sheaf of R-modules on M. I will discuss a variation of this construction that allows R to be a ring spectrum. This work is joint with Xin Jin.
