# Multi-fluid cosmology in Einstein gravity: analytical solutions

@inproceedings{Faraoni2021MultifluidCI, title={Multi-fluid cosmology in Einstein gravity: analytical solutions}, author={Valerio Faraoni and Sonia Jose and Steve Dussault}, year={2021} }

We review analytical solutions of the Einstein equations which are expressed in terms of elementary functions and describe Friedmann-Lemaître-Robertson-Walker universes sourced by multiple (real or effective) perfect fluids with constant equations of state. Effective fluids include spatial curvature, the cosmological constant, and scalar fields. We provide a description with unified notation, explicit and parametric forms of the solutions, and relations between different expressions present in…

The Theory of Special Relativity is an axiomatic theory, derived from two main axioms: the laws of physics are the same in all inertial frames (the principle of relativity) and the speed of light is determined by the Laws of physics.
