Geometric Horizons
Alan A. Coley, David D. McNutt, Andrey A. Shoom
We discuss black hole spacetimes with a geometrically defined quasi-local horizon on which the curvature tensor is algebraically special relative to the alignment classification. B…
Identification of black hole horizons using scalar curvature invariants
Alan Coley, David McNutt
We introduce the concept of a geometric horizon, which is a surface distinguished by the vanishing of certain curvature invariants which characterize its special algebraic characte…
Cartan Invariants and Event Horizon Detection, Extended Version
D. D. McNutt, M. A. H. MacCallum, D. Gregoris +4
We show that it is possible to locate the event horizons of a black hole (in arbitrary dimensions) as the zeros of certain Cartan invariants. This approach accounts for the recent…
Curvature invariant characterization of event horizons of four-dimensional black holes conformal to stationary black holes
David D. McNutt
We introduce three approaches to generate curvature invariants that transform covariantly under a conformal transformation of a four dimensional spacetime. For any black hole confo…
Scalar Polynomial Curvature Invariant Vanishing on the Event Horizon of Any Black Hole Metric Conformal to a Static Spherical Metric
David D. McNutt, Don N. Page
We construct a scalar polynomial curvature invariant that transforms covariantly under a conformal transformation from any spherically symmetric metric. This invariant has the addi…
The Cartan Algorithm in Five Dimensions
D. D. McNutt, A. A. Coley, A. Forget
In this paper we introduce an algorithm to determine the equivalence of five dimensional spacetimes, which generalizes the Karlhede algorithm for four dimensional general relativit…
