AbstractWe study the asymptotics of the natural L2 metric on the Hitchin moduli space with group $${G = \mathrm{SU}(2)}$$G=SU(2). Our main result, which addresses a detailed conjectural picture made by Gaiotto et al. (Adv Math 234:239–403, 2013), is that on the regular part of the Hitchin system, this metric is well-approximated by the semiflat metric from Gaiotto et al. (2013). We prove that the asymptotic rate of convergence for gauged tangent vectors to the moduli space has a precise… Expand
Asymptotics of Hitchin’s Metric on the Hitchin Section
We consider Hitchin’s hyperkähler metric g on the moduli space $${\mathcal{M}}$$M of degree zero SL(2)-Higgs bundles over a compact Riemann surface. It has been conjectured that, when one goes toExpand
Exponential Decay for the Asymptotic Geometry of the Hitchin Metric
We consider Hitchin’s hyperkähler metric $$g_{L^2}$$ g L 2 on the SU ( n )-Hitchin moduli space over a compact Riemann surface. We prove that the difference between the metric $$g_{L^2}$$ g L 2 and aExpand
The Ooguri-Vafa space as a moduli space of framed wild harmonic bundles
The Ooguri-Vafa hyperkahler metric is expected to be part of the local model of the $L^2$-hyperkahler metric of the Hitchin moduli spaces, near the generic part of the discriminant locus (seeExpand
Hyperk\"ahler metrics on the moduli space of weakly parabolic Higgs bundles
We use the theory of Gaiotto, Moore and Neitzke to construct a set of Darboux coordinates on the moduli space M of weakly parabolic SL(2,C)-Higgs bundles. For generic Higgs bundles (E , RΦ) with R 0Expand
ASYMPTOTIC GEOMETRY OF THE MODULI SPACE OF PARABOLIC SL(2, C)-HIGGS BUNDLES

Generic Ends of the Moduli Space of $SL(n,\mathbb{C})$-Higgs Bundles

$L^2$-cohomology of quasi-fibered boundary metrics
We develop new techniques to compute the weighted L-cohomology of quasi-fibered boundary metrics (QFB-metrics). Combined with the decay of L-harmonic forms obtained in a companion paper, this allowsExpand
Opers and nonabelian Hodge: numerical studies
We present numerical experiments that test the predictions of a conjecture of Gaiotto-Moore-Neitzke and Gaiotto concerning the monodromy map for opers, the nonabelian Hodge correspondence, and theExpand
