The second Dirac eigenvalue of a nearly parallel $G_2$-manifold

Differential Geometry 2011-04-06 v1

Abstract

We investigate the second Dirac eigenvalue on Riemannian manifolds admitting a Killing spinor. In small dimensions the whole Dirac spectrum depends on special eigenvalues on functions and 1-forms. We compute and discuss the formulas in dimension n=7n = 7.
