Excision without excision: the relativistic turducken
David Brown, Olivier Sarbach, Erik Schnetter +4
to turducken (turduckens, turduckening, turduckened, turduckened) [math.]: To stuff a black hole. We analyze and apply an alternative to black hole excision based on smoothing the…
The Midpoint Rule as a Variational--Symplectic Integrator. I. Hamiltonian Systems
David Brown
Numerical algorithms based on variational and symplectic integrators exhibit special features that make them promising candidates for application to general relativity and other co…
Conformal invariance and the conformal-traceless decomposition of the gravitational field
David Brown
Einstein's theory of general relativity is written in terms of the variables obtained from a conformal--traceless decomposition of the spatial metric and extrinsic curvature. The d…
Reference Fluids as Standards of Space and Time
David Brown
The idea that spacetime points are to be identified by a fleet of clock--carrying particles can be traced to the earliest days of general relativity. Such a fleet of clocks can be…
Black Hole Thermodynamics in a Box
David Brown
Simple calculations indicate that the partition function for a black hole is defined only if the temperature is fixed on a finite boundary. Consequences of this result are discusse…
