Abstract

top
In this note we prove some results in flat and differential K -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 K -theory and Freed-Lott differential K -theory.
