Refined hexagons for differential cohomology

Algebraic Topology 2014-12-09 v2

Abstract

Cheeger-Simons differential characters and differential KK-theory are refinements of ordinary cohomology theory and topological KK-theory respectively, and they are examples of differential cohomology. Each of these differential cohomology theories fits into a hexagon on the cohomology level. We show that these differential cohomology theories fit into hexagons on the cocycle level, and the hexagons on the cocycle level induce the hexagons on the cohomology level.
