Rigidity and uniqueness with matter: full Kerr–Newman regime
partial Rigidity / Uniqueness
Statement
Prove the full stationary uniqueness and perturbative rigidity theory for Kerr–Newman without smallness assumptions.
Mathematical prerequisites
Einstein–Maxwell stationary reduction; coupled invariant tensors; horizon regularity; unique continuation.
Why it matters
Kerr–Newman is the natural charged rotating family, but its full rigidity theory is still not as complete as one would like.
Completion criteria
A complete answer must characterize the full stationary family under natural hypotheses and support the coupled dynamical theory.
Implications if solved
Would unify the stationary Einstein–Maxwell black-hole classification.
