Gibbons–Hawking space
Manifold in mathematical physics
From Wikipedia, the free encyclopedia
In mathematical physics, a Gibbons–Hawking space, named after Gary Gibbons and Stephen Hawking, is essentially a hyperkähler manifold with an extra U(1) symmetry.[1] (In general, Gibbons–Hawking metrics are a subclass of hyperkähler metrics.[2]) Gibbons–Hawking spaces, especially ambipolar ones,[3] find an application in the study of black hole microstate geometries.[1][4]
