On the wall-crossing formula for quadratic differentials
We prove an analytic version of the Kontsevich-Soibelman wall-crossing
formula describing how the number of finite-length trajectories of a quadratic
differential jumps as the differential is varied. We characterize certain maps
appearing in this wall-crossing formula using Fock-Goncharov coordinates. As an
application, we compute the Stokes automorphisms for Voros symbols in exact WKB
analysis.Comment: 36 page
