Description
We present the leading order nonlinear density and velocity power spectra
including the vector- and tensor-type perturbation simultaneously excited
by the scalar-type perturbation in nonlinear order.
Concerning density and velocity perturbations of the pressureless matter
in perturbation regime well inside of matter-dominated epoch, we show that
pure Einstein’s gravity contributions appearing from the third order are
entirely negligible in all scales.
