Zusammenfassung: | We construct a scattering theory for the spin \(\pm2\) Teukolsky equations on the exterior of the Schwarzschild spacetime, as a first step towards developing a scattering theory for the linearised Einstein equations in double null gauge. This is done by exploiting a physical-space version of the Chandrasekhar transformation used by Dafermos, Holzegel and Rodnianski in [arxiv:1601.06467] to prove the linear stability of the Schwarzschild solution. We also address the Teukolsky-Starobinsky correspondence and construct an isomorphism between scattering data for the \(+2\) and \(-2\) Teukolsky equations. This will allow us to state an additional mixed scattering statement for a pair of curvature components satisfying the spin \(+2\) and \(-2\) Teukolsky equations and connected via the Teukolsky-Starobinsky identities, completely determining the radiating degrees of freedom of solutions to the linearised Einstein equations. |
