Relations between chern number and edge state

  1. Apr 22, 2015 #1
    I have been doing a literature survey about topological insulators for some time. What surprises me is the close relation between difference of chern number and number of edge states. However, I found most review or tutorial in topological insulator avoided direct proof of the relation. So can someone tell me where the rigorous proof of the relation can be found?
