Abstract
We investigate large-scale cosmological perturbation in the Universe with multiple perfect fluids. Using the long-wavelength approximation with the Hamilton-Jacobi method, we derive a formula for the gauge-invariant comoving curvature perturbation. As an application of our approach, we examine large-scale perturbation in a brane cosmology.
