Categorified sheaf theory and the spectral Betti Langlands TQFT

Abstract: It is expected that the Betti form of the geometric Langlands equivalence will ultimately fit into an equivalence of four dimensional topological field theories. In this talk I will give an overview of ongoing work in the theory of sheaves of higher categories in derived algebraic geometry, and explain how it can be used to define a candidate four dimensional theory for the spectral side.
