On the absolutely continuous spectrum of the Laplace-Beltrami operator acting on p-forms for a class of warped product metrics

Francesca Antoci

We explicitely compute the absolutely continuous spectrum of the Laplace-Beltrami operator for -forms for the class of warped product metrics $dσ^2= y^{2a}dy^2 + y^{2b}dθ_{\Sphe…
