AR2W01 - Physical resurgence: On quantum, gauge, and stringy

address the resurgence properties of the WKB expansions for the stationary Schrödinger equation in one dimension, with a polynomial potential, and the associated Riccati equation. We decompose the relevant series as infinite sums, indexed by words or decorated trees, of simpler components and prove, for these functions, the crucial property of endless analytic continuability in the Borel plane.
