Spectral Bounds for Dirac Operators on Open Manifolds
Christian Baer
We extend several classical eigenvalue estimates for Dirac operators on compact manifolds to noncompact, even incomplete manifolds. This includes Friedrich's estimate for manifolds…

The Dirac Operator on Nilmanifolds and Collapsing Circle Bundles
Bernd Ammann, Christian Baer
We compute the spectrum of the Dirac operator on 3-dimensional Heisenberg manifolds. The behavior under collapse to the 2-torus is studied. Depending on the spin structure either a…
