Coarse geometry and topological phases Meyer, Ralf


We propose the Roe C*-algebra from coarse geometry as a model for topological phases of disordered materials. We explain the robustness of this C*-algebra and formulate the bulk-edge correspondence in this framework. We describe the map from the K-theory of the group C*-algebra of $Z^d$ to the K-theory of the Roe C*-algebra, both for real and complex K-theory. (Article with Elke Ewert)
