On a lower bound for the first eigenvalue of the Laplace operator on a riemannian manifold
A compactification of a manifold with asymptotically nonnegative curvature
Convergence of Riemannian manifolds and Laplace operators. I
We study the spectral convergence of compact Riemannian manifolds in relation with the Gromov-Hausdorff distance and discuss the geodesic distances and the energy forms of the limit spaces.
