Local invariants vanishing on stationary horizons: a diagnostic for locating black holes.

چکیده
Inspired by the example of Abdelqader and Lake for the Kerr metric, we construct local scalar polynomial curvature invariants that vanish on the horizon of any stationary black hole: the squared norms of the wedge products of n linearly independent gradients of scalar polynomial curvature invariants, where n is the local cohomogeneity of the spacetime.

Conformal Symmetries of the Einstein-Hilbert Action on Horizons of Stationary and Axisymmetric Black Holes
We suggest a way to study possible conformal symmetries on black hole horizons. We do this by carrying out a Kaluza-Klein like reduction of the Einstein-Hilbert action along the ignorable coordinates of stationary and axisymmetric black holes. Rigid diffeomorphism invariance of the m-ignorable coordinates then becomes a global SL(m,R) gauge symmetry of the reduced action. Related to each non-va...
متن کاملON HIGHER DIMENSIONAL BLACK HOLES WITH ABELIAN ISOMETRY GROUP by
— We consider (n + 1)–dimensional, stationary, asymptotically flat, or Kaluza-Klein asymptotically flat black holes, with an abelian s–dimensional subgroup of the isometry group satisfying an orthogonal integrability condition. Under suitable regularity conditions we prove that the area of the group orbits is positive on the domain of outer communications 〈〈Mext〉〉, vanishing only on the boundar...
متن کاملThe inner Cauchy horizon of axisymmetric and stationary black holes with surrounding matter
We investigate the interior of regular axisymmetric and stationary black holes surrounded by matter and find that for non-vanishing angular momentum of the black hole the spacetime can always be extended regularly up to and including an inner Cauchy horizon. We provide an explicit relation for the regular metric at the inner Cauchy horizon in terms of that at the event horizon. As a consequence...
متن کاملOn the existence of horizons in spacetimes with vanishing curvature invariants
A direct very simple proof that there can be no closed trapped surfaces (ergo no black hole regions) in spacetimes with all curvature scalar invariants vanishing is given. Explicit examples of the recently introduced “dynamical horizons” which nevertheless do not enclose any trapped region are presented too.
متن کاملFundamental properties and applications of quasi-local black hole horizons
The traditional description of black holes in terms of event horizons is inadequate for many physical applications, especially when studying black holes in non-stationary spacetimes. In these cases, it is often more useful to use the quasi-local notions of trapped and marginally trapped surfaces, which lead naturally to the framework of trapping, isolated and dynamical horizons. This framework ...
