DESCRIPTION:Marcos Marino\nThe building blocks of quantum observables are 
 collections of asymptotic series in the coupling constant\, corresponding 
 to perturbative and non-perturbative sectors. According to the theory of r
 esurgence\, these series are related to each other in a non-trivial way\, 
 and these relations are encoded in the so-called Stokes automorphisms of t
 he theory. In this seminar we put forward the idea that knowledge of these
  automorphisms and of the classical limit might make it possible to solve 
 the quantum theory at all values of the coupling. We show how this program
  can be implemented in detail in quantum mechanics with polynomial potenti
 als.\nIn this case\, the solution takes the form of a set of coupled integ
 ral equations of the TBA type\, which generalizes the famous ODE/IM corres
 pondence. This implementation uses ideas about BPS states and their wall-c
 rossing in supersymmetric gauge theories
