Appendix: Basic Equations and Numerical Methods
Some basic equations relevant for fully relativistic as well as
perturbative cosmological calculations are summarized in this
section, including the complete Einstein equations, choices of
kinematical conditions, initial data constraints,
stress-energy-momentum tensors, dynamical equations for various
matter sources, and the Newtonian counterparts on background
isotropic models. References to numerical methods are also
provided.
