Exploring (geometrically engineered) 5d BPS spectra

We will develop geometric techniques for counting BPS states in five-dimensional gauge theories engineered by M theory on a toric Calabi-Yau threefold. The problem is approached by studying framed 3d-5d wall-crossing in presence of a single M5 brane wrapping a special Lagrangian submanifold L. The spectrum of 3d-5d BPS states is encoded by the geometry of the manifold of vacua of the 3d-5d system, which further coincides with the mirror curve describing moduli of the Lagrangian brane. The information about the BPS spectrum is extracted from the geometry of the mirror curve by construction of a nonabelianization map for the exponential networks. We will start by reviewing exponential networks, sketch the computation for a particular toric Calabi-Yau threefold. Finally, we will finish by remarking about several aspects of enumerative invariants for the Calabi-Yau threefolds.
