Cosmological status of Lagrangian theory of density perturbations
arXiv:astro-ph/0612397 · doi:10.1134/S1063772907060017
Abstract
We show that hydrodynamical and field approaches in theory of cosmological scalar perturbations are equivalent for a single medium. We also give relations between notations introduced by V. Lukash, J. Bardeen, J. Bardeen et al. and G. Chibisov and V. Mukhanov.
