Abstract
We consider Hitchin’s hyperkähler metric g on the moduli space \({\mathcal{M}}\) of degree zero SL(2)-Higgs bundles over a compact Riemann surface. It has been conjectured that, when one goes to infinity along a generic ray in \({\mathcal{M}}\), g converges to an explicit “semiflat” metric gsf, with an exponential rate of convergence.We show that this is indeed the case for the restriction of g to the tangent bundle of the Hitchin section \({\mathcal{B} \subset \mathcal{M}}\).
