Stokes phenomenon in Chern-Simons theory

In my talk I will review the Stokes phenomenon of perturbative expansions of oscillatory integrals (from the perspective of Picard-Lefschetz theory) and the notion of analytically continued Chern-Simons theory. I will then tell how one can explicitly calculate Stokes constants in Chern-Simons theory on 3-manifolds of certain types. If time permits, I will also comment on categorification of the Stokes constants..
