Non-Commutative Geometry in Higher Dimensional Quantum Hall Effect as   A-Class Topological Insulator
  We clarify relations between the higher dimensional quantum Hall effect and A-class topological insulator. In particular, we elucidate physical implications of the higher dimensional non-commutative geometry in the context of A-class topological insulator. This presentation is based on arXiv:1403.5066.
