Inverse scattering for Kerr parameters

open Spectral / Scattering

Statement

Determine whether scattering data for a natural field equation uniquely and stably determine the Kerr mass and spin.

Mathematical prerequisites

Inverse scattering; geometric optics; spectral invariants; uniqueness and stability estimates for parameter recovery.

Why it matters

The forward scattering map on Kerr is rich enough that one expects inverse geometric information to be hidden in it.

Completion criteria

A complete answer must specify the data set, prove uniqueness of (M,a), and give quantitative stability estimates.

Implications if solved

Would turn black-hole scattering into a geometric inverse problem with direct interpretive value.
