Abstract

For eigenvalues of generalized Dirac operators on compact Riemannian manifolds, we obtain a general inequality. By using this inequality, we study eigenvalues of generalized Dirac operators on compact submanifolds of Euclidean spaces, of spheres, and of real, complex and quaternionic projective spaces. We obtain explicit bounds for the (k + 1)‐th eigenvalue of generalized Dirac operators on such objects in terms of its first k eigenvalues, which depend on the mean curvature of the embedding and the curvature term in the Bochner‐Weitzenböck formula for the square of the Dirac operator. These inequalities of eigenvalues extend the recent results in 15. © 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim

## Abstract We study the asymptotic behavior of the eigenvalues and the eigenfunctions of the Laplace–Beltrami operator on a Riemannian manifold __M__^ε^ depending on a small parameter ε>0 and whose structure becomes complicated as ε→0. Under a few assumptions on scales of __M__^ε^ we obtain the ho

This paper is devoted to a general min-max characterization of the eigenvalues in a gap of the essential spectrum of a self-adjoint unbounded operator. We prove an abstract theorem, then we apply it to the case of Dirac operators with a Coulomb-like potential. The result is optimal for the Coulomb p
