Wall Crossing Invariants from Spectral Networks
Wall Crossing Invariants from Spectral Networks
A new construction of BPS monodromies for 4d $${\mathcal {N}}=2$$ theories of class $${\mathcal {S}}$$ is introduced. A novel feature of this construction is its manifest invariance under Kontsevich–Soibelman wall crossing, in the sense that no information on the 4d BPS spectrum is employed. The BPS monodromy is encoded by …
