Coronas and Callias type operators in coarse geometry

Ulrich Bunke, Matthias Ludewig

We interpret the coarse symbol and index class of a Callias type Dirac operator on a manifold as a pairing between the coarse symbol and index classes associated to a…

Coarse geometric approach to topological phases: Invariants from real-space representations

Christoph S. Setescak, Caio Lewenkopf, Matthias Ludewig

We show that topological phases include disordered materials if the underlying invariant is interpreted as originating from coarse geometry. This coarse geometric framework, ground…
