On the non-Archimedean Hitchin map for $SL_{2} (F)$

Jiahuang Chen, Siqi He

Let $F$ be a non-Archimedean valued field, $Σ$ a closed Riemann surface of genus at least two, and $Γ$ its fundamental group. Building on the theory of equivariant harmonic maps in…

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…
