摘要

Bardeen's formalism for cosmological perturbations is extended to a system of a fluid and a collisionless gas which is the best candidate for the dark matter. For the latter kinetic approach is taken and the linearized coupled Einstein-Boltzmann equations are derived. When we solve them, any truncation is not performed in our formalism. Because of gauge-invariance, it is suited especially to the study of perturbations of the dark matter in an early stage of the universe, which grow to eventually form the large scale structure of the universe.
