Scattering theory for linearized gravity on Kerr

partial Spectral / Scattering

Statement

Construct a complete gauge-invariant scattering theory for linearized vacuum Einstein perturbations on Kerr, paralleling the scalar-wave case.

Mathematical prerequisites

Gauge fixing; Teukolsky-to-metric reconstruction; horizon and infinity radiation fields; asymptotic completeness for constrained systems.

Why it matters

Decay results are stronger when organized into a full scattering theory.

Completion criteria

A complete answer must define the scattering states, wave operators, and asymptotic completeness modulo stationary/gauge modes.

Implications if solved

Would give the definitive linearized-gravity input for both exterior stability and interior genericity problems.
