Exponential BPS graphs and D-brane counting on toric Calabi-Yau threefolds: Part II

Sibasish Banerjee, Pietro Longhi, Mauricio Romo

We study BPS states of 5d $\mathcal{N}=1$ $SU(2)$ Yang-Mills theory on $S^1\times {\mathbb{R}}^4$. Geometric engineering relates these to enumerative invariants for the local Hirzebr…
