| Abstract;The framework is presented, as general as possible, to formulate the cosmological perturbation of a universe in which multi-component scalar fields dominate during the inflation. The .DELTA.N formula, which relates the curvature perturbation to the inflaton perturbation, is extended to derive the evolution equation for the curvature perturbation. The power spectrum of the curvature perturbation is computed in the multi-component general slow-roll inflation. |
