Abstract: The Stokes phenomenon, discovered in the study of Airy function around 185 7, describes the jump of asymptotics of solutions of meromorphic linear ODEs at irregular singularities. This talk gives an introduction to the Stokes phenom enon. It then relates the Stokes matrices in the WKB approximation, of a mer omorphic ODE, with the periods on the underlying spectral curves.
