Manifestly gauge invariant theory of the nonlinear cosmological perturbations in the leading order of the gradient expansion
Takashi Hamazaki
In the full nonlinear cosmological perturbation theory in the leading order of the gradient expansion, all the types of the gauge invariant perturbation variables are defined. The…

Long wavelength limit of evolution of cosmological perturbations in the universe where scalar fields and fluids coexist
Takashi Hamazaki
We present the LWL formula which represents the long wavelengh limit of the solutions of evolution equations of cosmological perturbations in terms of the exactly homogeneous solut…

Evolution of Cosmological Perturbations in the Universe dominated by Multiple Scalar Fields
Takashi Hamazaki
By efforts of several authors, it is recently established that the dynamical behavior of the cosmological perturbation on superhorizon scales is well approximated in terms of that…
