Abstract: The generating function of higher genus Gromov-Witten invariants of Calabi-Yau threefolds can be computed by topological string theory and is given by an asymptotic series in the topological string coupling. I will discuss how a piecewise analytic function in the string coupling can be obtained from this series via resurgence analysis and how Donaldson-Thomas invariants of the same geometry can be obtained from the corresponding Stokes factors. This is based on various joint works with Lotte Hollands, Arpan Saha, Iván Tulli and Jörg Teschner as well as on work in progress.
