The non-perturbative topological string: from resurgence to wall-crossing of DT invariants
Simon Douaud, Amir-Kian Kashani-Poor
We study the resurgence structure of the topological string partition function, with an emphasis on the Borel analysis of the instanton amplitudes. To this end, we introduce a diff…

The twisted geometry of 6d F-theory vacua with discrete gauge symmetries
David Jaramillo Duque, Amir-Kian Kashani-Poor, Thorsten Schimannek
We study the fate of discrete gauge groups and discrete charges of gravitational theories under twisted circle compactification. We then apply our results to six-dimensional F-theo…

Borel singularities and Stokes constants of the topological string free energy on one-parameter Calabi-Yau threefolds
Simon Douaud, Amir-Kian Kashani-Poor
We study the Borel plane of the topological string free energy on all hypergeometric one-parameter Calabi-Yau models close to singular points in moduli space, focusing on the locat…
