3d spectral networks and classical Chern-Simons theory
Daniel S. Freed, Andrew Neitzke
We define the notion of spectral network on manifolds of dimension . For a manifold equipped with a spectral network, we construct equivalences between Chern-Simons inva…
Asymptotics of Hitchin's metric on the Hitchin section
David Dumas, Andrew Neitzke
We consider Hitchin's hyperkähler metric on the moduli space of degree zero -Higgs bundles over a compact Riemann surface. It has been conjectured…
From -fixed points to -algebra representations
Laura Fredrickson, Andrew Neitzke
We study a set parameterizing filtered -Higgs bundles over with an irregular singularity at , such that the eigenvalues of th…
Integral iterations for harmonic maps
Andrew Neitzke
We study minimal harmonic maps , parameterized by polynomial cubic differentials in the plane. The asymptotic structure…
Opers versus nonabelian Hodge
Olivia Dumitrescu, Laura Fredrickson, Georgios Kydonakis +3
For a complex simple simply connected Lie group , and a compact Riemann surface , we consider two sorts of families of flat -connections over . Each family is determine…
Notes on a new construction of hyperkahler metrics
Andrew Neitzke
We review a construction of hyperkahler metrics proposed in joint work of Davide Gaiotto, Greg Moore and the author. A key ingredient in this construction is a collection of intege…
