Eigenvalue estimate for the Dirac-Witten operator on locally reducible Riemannian manifolds
Yongfa Chen
We get optimal lower bounds for the eigenvalues of the Dirac-Witten operator on locally reducible spacelike submanifold in terms of intrinsic and extrinsic expressions. The limitin…

The Dirac operator on locally reducible Riemannian manifolds
Yongfa Chen
In this paper, we get estimates on the higher eigenvalues of the Dirac operator on locally reducible Riemannian manifolds, in terms of the eigenvalues of the Laplace-Beltrami opera…
