Chern-Simons classes of flat connections on supermanifolds
arXiv:0707.2321
Abstract
In this note we define Chern-Simons classes of a superconnection on a complex supervector bundle such that is flat and preserves the grading, and is an odd endomorphism of on a supermanifold. As an application we obtain a definition of Chern-Simons classes of a (not necessarily flat) morphism between flat vector bundles on a smooth manifold. We extend Reznikov's theorem on triviality of these classes when the manifold is a compact Kähler manifold or a smooth complex quasi--projective variety, in degrees > 1.
