Eigenvalue estimates of the Dirac operator depending on the Ricci tensor

Differential Geometry 2007-05-23 v1

Abstract

We prove a new lower bound for the first eigenvalue of the Dirac operator on a compact Riemannian spin manifold by refined Weitzenb\"ock techniques. It applies to manifolds with harmonic curvature tensor and depends on the Ricci tensor. Examples show how it behaves compared to other known bounds.
