• Higher-order Lagrangian perturbation for structure formation in the Universe

抄録

The structure formation in the Universe has been known as one of the most important problem in modern cosmology. The formation causes its self-gravitating instability and cosmic expansion. Therefore when we analyze the structure obtained by the observations, we would know the evolution of the Universe. We have derived fifth-order perturbative equations in Lagrangian perturbation theory for a cosmological dust fluid. These equations are derived under the supposition of Newtonian cosmology in the Friedmann-Lemaitre-Robertson-Walker Universe model. The application of the fifth-order perturbation leads to a precise prediction of the large-scale structure.
