TY - JOUR A1 - Bär, Christian T1 - Spectral bounds for Dirac operators on open manifolds N2 - We extend several classical eigenvalue estimates for Dirac operators on compact manifolds to noncompact, even incomplete manifolds. This includes Friedrich's estimate for manifolds with positive scalar curvature as well as the author's estimate on surfaces.
