Exact inhomogeneous EinsteinLiouville solutions in RobertsonWalker spacetimes
Abstract
We give the general solution of Liouville's equation in RobertsonWalker spacetimes, and use this to find exact inhomogeneous EinsteinLiouville solutions, using the covariant harmonic method of Ellis, Matravers and Treciokas [1]. The average fourvelocity of the gas is tilted, and the gas has nonzero acceleration, shear, energy flux, and anisotropic stress.
