Optimal eigenvalues estimate for the Dirac operator on domains with boundary

arXiv:math/0603512 · doi:10.1007/s11005-005-0005-y

Abstract

We give a lower bound for the eigenvalues of the Dirac operator on a compact domain of a Riemannian spin manifold under the $\MIT$ bag boundary condition. The limiting case is characterized by the existence of an imaginary Killing spinor.
