Eigenvalue estimates for hypersurfaces in $H^m \times R$ and applications
Résumé
In this paper, we give a lower bound for the spectrum of the Laplacian on minimal hypersurfaces immersed into $H^m \times R$. As an application, in dimension 2, we prove that a complete minimal surface with finite total extrinsic curvature has finite index. On the other hand, for stable, minimal surfaces in $H^3$ or in $H^2 \times R$, we give an upper bound on the infimum of the spectrum of the Laplacian and on the volume growth.
