Non-perturbative corrections to 3d BPS indices and topological strings

Abstract For a 3d gauged linear sigma model parametrized by a Kähler manifold X, the 3d BPS index defines a q-series that can be analytically continued in the Kähler modulus by standard methods. It is argued that an SL(2, ℤ)-transform of the Birkhoff connection matrix captures non-perturbative corre...
