A complete gauge-invariant formalism for arbitrary second-order perturbations of a Schwarzschild black hole
David Brizuela, Jose M. Martin-Garcia, Manuel Tiglio
Using recently developed efficient symbolic manipulations tools, we present a general gauge-invariant formalism to study arbitrary radiative second-order perturbations…
Petrov D vacuum spaces revisited: Identities and Invariant Classification
S. Brian Edgar, Alfonso García-Parrado Gómez-Lobo, José M. Martín-García
For Petrov D vacuum spaces, two simple identities are rederived and some new identities are obtained, in a manageable form, by a systematic and transparent analysis using the GHP f…
xPert: Computer algebra for metric perturbation theory
David Brizuela, Jose M. Martin-Garcia, Guillermo A. Mena Marugan
We present the tensor computer algebra package xPert for fast construction and manipulation of the equations of metric perturbation theory, around arbitrary backgrounds. It is base…
