DESCRIPTION:After reviewing the well-established notion of bla
ck-hole perturbation theory and the concept of qua
sinormal modes\, we present a spectral representat
ion of solutions to relativistic wave equations ba
sed on a geometrical approach in which the constan
t-time surfaces extend until future null infinity.
Here\, we restrict ourselves to an asymptotically
flat\, spherical symmetric spacetime (with focus
on the Reissner-Nordstrom solution). With the help
of a Laplace transformation on the wave equation
in question\, we provide a geometrical interpretat
ion to known algorithms (i.e. Leaverâ€™s approach) a
part from deriving an algorithm for obtaining all
ingredients of the desired spectral decomposition\
, including quasi-normal modes\, quasi-normal mode
amplitudes as well as the jump of the Laplace-tra
nsform along the branch cut.
