The asymptotics of the ${\mathrm{SL}}_2(\mathbb{C})$-Hitchin metric on the singular locus: subintegrable systems

Siqi He, Johannes Horn, Nianzi Li

We study the asymptotic hyperkähler geometry of the ${\mathrm{SL}}_2(\mathbb{C})$-Hitchin moduli space over the singular fibers of the Hitchin fibration. We extend the previously kno…
