1208.5462 (Ralph M. Kaufmann et al.)

The noncommutative geometry of wire networks from triply periodic
surfaces
   [PDF]

Ralph M. Kaufmann, Sergei Khlebnikov, Birgit Wehefritz-Kaufmann
We study wire networks that are the complements of triply periodic minimal surfaces. Here we consider the P, D, G surfaces which are exactly the cases in which the corresponding graphs are symmetric and self-dual. Our approach is using the Harper Hamiltonian in a constant magnetic field. We treat this system with the methods of noncommutative geometry and obtain a classification for all the $C^*$ geometries that appear.
