On the Spectrum of Non-Compact Manifolds with Finite Volume.
On the spectrum of Riemannian submersions with totally geodesic fibers
In this Note we give a rule to compute explicitely the spectrum and the eigenfunctions of the total space of a Riemannian submersion with totally geodesic fibers, in terms of the spectra and eigenfunctions of the typical fiber and any associated principal bundle.
