Dominik J. Schwarz
TL;DR
This paper derives exact solutions for cosmological perturbations in a radiation-dominated universe with collisionless matter using a generalized power series approach.
Contribution
It provides a comprehensive method to obtain all regular and singular perturbation solutions in this cosmological setting.
Findings
All perturbations can be expressed via a generalized power series.
The solutions include both regular and singular cases.
The method offers a complete characterization of perturbations in the model.
Abstract
All regular and singular cosmological perturbations in a radiation dominated Einstein-de Sitter Universe with collisionless particles can be found by a generalized power series ansatz. Talk given at "Birth of the Universe and Fundamental Physics", May 1994 (Rome).
