Scattering map to the Cauchy horizon for linearized gravity

partial Interior / SCC

Statement

Construct a precise scattering map from exterior or horizon data to asymptotic data at the Kerr Cauchy horizon for gravitational perturbations.

Mathematical prerequisites

Teukolsky separation; physical-space asymptotics; scattering operators in non-globally-hyperbolic regions; gauge reconstruction.

Why it matters

The Cauchy horizon is best understood through a precise data-to-asymptotics map.

Completion criteria

A complete answer must define the map in explicit norms and prove sharp asymptotic formulas, including generic leading coefficients.

Implications if solved

Would clarify how exterior information is reprocessed by the blue-shift region.
