Resurgence through Path Integrals
Appears in collections : Resurgence in Mathematics and Physics, Fields medallists - 1998, Maxim Kontsevich
I will review the approach to the resurgence phenomenon via integration overrapid decay cycles (Lefschetz thimbles) in path integrals. Examples include WKB asymptotics, heat kernels, WZW models and Chern-Simons theory.
