The PerturbationEquations Mathematica package provides a set of tools for working with spherical-harmonic decompositions of the first- and second-order Einstein equations and with the Teukolsky equations in Schwarzschild spacetime. See the package website for further details and installation instructions.

What's Changed

  • Added support for hyperboloidal slicing via a height function.
  • Added Master Teukolsky operator to SchwarzschildLinearOperator.
  • Added support for the Hartle-Hawking tetrad.
  • Added "Master" OutputBasis option for S_0 and S_4 in SchwarzschildQuadraticCovariantSource.
  • Fixed missing factors of 2 in master Teukolsky equation source.
  • Fixed a missing factor of r^2 in the definition of the master Teukolsky equation source.
  • Removed spurious factor of 1/(8Pi) in S0d2G and S4d2G.
