Dirac eigenvalues estimates in terms of symmetric tensors
arXiv:0909.1417
Abstract
We review some recent results concerning lower eigenvalues estimates for the Dirac operator [6, 7]. We show that Friedrich's inequality can be improved via certain well-chosen symmetric tensors and provide an application to Sasakian spin manifolds.
