Stability and uniqueness of Kerr black holes

This text mentions work from 2024 on. Those parts were partly written without a live literature search and have not been checked by an editor yet.

The Kerr solution describes a spinning black hole in Einstein's theory. To be the endpoint of real collapses it must be the only settled black hole and must be stable: when slightly disturbed, it should settle back to another Kerr black hole.

Why it matters

Stability and uniqueness underpin the use of Kerr black holes as the final state of every astrophysical merger and of every ringdown test.
