Transgression of the index gerbe
Ulrich Bunke
Recently, for a family of ungraded Dirac operators over some space J. Lott constructed an index gerbe. In the present paper we show (in analogy to the holonomy formula for the…
Nonexistence of invariant distributions supported on the limit set
Ulrich Bunke, Martin Olbrich
We obtain sufficient conditions exlcuding the existence of non-trivial distribution sections of bundles over the boundary of symmetric spaces of negative curvature which are invari…
Index and secondary index theory for flat bundles with duality
U. Bunke, X. Ma
We discuss some aspects of index and secondary index theory for flat bundles with duality. This theory was first developed by J. Lott. Our main purpose in the present paper is to p…
Regularity of invariant distributions
Ulrich Bunke, Martin Olbrich
We consider a geometrically finite discrete group of conformal transformations of the sphere. Further we consider distributions which are supported on the limit set and are invaria…
