Exact solutions in general relativity | Metric tensors
The Kerr metric or Kerr geometry describes the geometry of empty spacetime around a rotating uncharged axially symmetric black hole with a quasispherical event horizon. The Kerr metric is an exact solution of the Einstein field equations of general relativity; these equations are highly non-linear, which makes exact solutions very difficult to find. (Wikipedia).

Peter Hintz: Linear stability of slowly rotating Kerr spacetimes
I will describe joint work with Dietrich Häfner and Andràs Vasy in which we study the asymptotic behavior of linearized gravitational perturbations of Schwarzschild or slowly rotating Kerr black hole spacetimes. We show that solutions of the linearized Einstein equation decay at an inverse

Strange Properties of Spinning Black Holes - Kerr Metric, General Relativity, Physics Explained
Hey everyone, I'm back with a video about black holes! This time, we're talking about spinning (rotating) black holes, and their rather interesting characteristics. The mathematical (and theoretical) properties of a rotating black hole are described by the Kerr metric. This metric is a s

Lars Andersson - Geometry and analysis in black hole spacetimes (Part 2)
Black holes play a central role in general relativity and astrophysics. The problem of proving the dynamical stability of the Kerr black hole spacetime, which is describes a rotating black hole in vacuum, is one of the most important open problems in general relativity. Following a brief i
