Real embeddings and eta invariants.
Remarks on flat and differential -theory
In this note we prove some results in flat and differential -theory. The first one is a proof of the compatibility of the differential topological index and the flat topological index by a direct computation. The second one is the explicit isomorphisms between Bunke-Schick differential -theory and Freed-Lott differential -theory.
Rigid versus non-rigid cyclic actions.
Rochlin invariants, theta functions and the holonomy of some determinant line bundles.
