Using a functional inequality, the essential spectrum and eigenvalues are estimated for Laplace-type operators on Riemannian vector bundles. Consequently, explicit upper bounds are obtained for the dimension of the corresponding L2-harmonic sections. In particular, some known results concerning Gromov’s theorem and the L2-Hodge decomposition are considerably improved. 2000 Mathematics Subject Classification: 58J50, 58J65. 1. Introduction. Recal
