The lower bound of the Ricci curvature that yields the infinite number of the discrete spectrum of the Laplacian
Abstract
This paper discusses the question whether the discrete spectrum of the Laplace-Beltrami operator is infinite or finite. The borderline-behavior of the curvatures for this problem will be completely determined.
