Wall-crossing formulas via spectral networks

Johannes Horn, Martin Möller

We give a self-contained proof of the Kontsevich-Soibelman wall-crossing formula entirely in the scope of quadratic differentials without relying on input from DT theory. Our appro…

The asymptotics of the $SL_{2} (C)$ -Hitchin metric on the singular locus: subintegrable systems

Siqi He, Johannes Horn, Nianzi Li

We study the asymptotic hyperkähler geometry of the $SL_{2} (C)$ -Hitchin moduli space over the singular fibers of the Hitchin fibration. We extend the previously kno…
