Nonmetrical description of cosmological perturbations

Physical Review D, 1992
The perturbed Friedmann universe is investigated and a gauge is searched for that defines coordinates "as close to the unperturbed background ones as possible." This characterization is formulated here in a more rigorous manner that allows in the case of vanishing background pressure a mathematical derivation of the desired gauge.
