Relations between Stokes constants of unrefined and Nekrasov-Shatashvili topological strings

Abstract In this paper we demonstrate that the Stokes constants of unrefined iphone 14 price arizona free energies and the Stokes constants of Nekrasov-Shatashvili free energies of topological string on a non-compact Calabi-Yau threefold are identical, possibly up to a sign, for any Borel singularity which is not associated to a compact two-cycle that ngetikin intersects only with non-compact four-cycles.Since the Stokes constants of Nekrasov-Shatashvili free energies are conjectured to coincide with those of quantum periods and therefore have the interpretation of BPS invariants, our results give strong support that the Stokes constants of unrefined free energies may also be identified with BPS invariants.
