# The bulk-edge correspondence in three simple cases

@article{Shapiro2017TheBC, title={The bulk-edge correspondence in three simple cases}, author={Jacob Shapiro}, journal={Reviews in Mathematical Physics}, year={2017} }

We present examples in three symmetry classes of topological insulators in one or two dimensions where the proof of the bulk-edge correspondence is particularly simple. This serves to illustrate the mechanism behind the bulk-edge principle without the overhead of the more general proofs which are available. We also give a new formula for the [Formula: see text]-index of our time-reversal invariant systems inspired by Moore and Balents.
