Dirac eigenvalues, hyperspherical radius and applications
Christian Bär (UP)
We give a new extrinsic upper bound for the smallest eigenvalues of the Dirac operator of a hypersurface. If the ambient manifold is the hyperbolic space, we show that its limiting case is achieved only for geodesic spheres.
