The Method of Comparison Equations for Schwarzschild Black Holes
Roberto Casadio, Mattia Luzzi
We employ the method of comparison equations to study the propagation of a massless minimally coupled scalar field on the Schwarzschild background. In particular, we show that this…

Method of comparison equations for cosmological perturbations
R. Casadio, F. Finelli, A. Kamenshchik +2
We apply the method of comparison equations to study cosmological perturbations during inflation, obtaining the full power spectra of scalar and tensor perturbations to first and t…
